In the plastic industry, many companies consider using blow molding technology to produce hollow products in order to save costs. This significantly reduces costs compared to injection molding,

Therefore, the methods of blow molding processing have also developed rapidly. Blow molded products are also suitable for a wide range of industries, such as the toy industry, packaging industry, electrical industry, and other industries.

The position of the mold separation (closing line), product slope, product layout, and appearance modification involved in the blow molding process are factors that mold engineers and blow molding engineers need to consider. The specific analysis is as follows:

1、 The positions of inserts, exhaust slots, intake needles, top pin holes, engraving, and labels need to be carefully considered.

2、 Check all usage functions. When used as a product, the fewer components and assembly work, the better, which can reduce the cost of the product.

3、 Inflation ratio. Pay attention to areas that trigger extremely thin geometric shapes, which may be protruding or recessed. When the width to depth ratio is too large, vacuum forming can be used as an aid.

4、 Principle of radius. Avoid sharp edges, corners, sudden changes in surface, sudden changes in product diameter or wall thickness.

5、 The slope of the product. All surfaces parallel to the direction of mold movement should have some slope, which should make it easy to open the mold and facilitate the removal of the product.

6、 The position of the mold line. Before opening the mold, the mold engineer needs to carefully consider how to divide the mold, as this will affect the subsequent production and appearance of the product.

Based on the above points, whether it is a small blow molded product or a large blow molded product, the energy and time required for development cannot be reduced. Factors that may affect the blow molding processing effect must be carefully considered in order to match the appearance and function of each blow molded product.

There are various types of blow molding molds in Shanghai, with different structural compositions and design requirements.

The main requirements for extrusion blowing molds are:

① The inflation ratio should be appropriate, and the distribution of various parts of the product should be as uniform as possible;

② Can effectively clamp the billet, and the strength of the joint at the clamp is sufficient;

③ Reliable exhaust ensures rapid expansion of the billet and adherence to the mold wall;

④ Cooling is fast and uniform.

Mold cavity design:

A parting surface: usually the plane that passes through the largest part of the product's cross-sectional profile. Products with complex shapes can have curved surfaces or be composed of multiple flat surfaces. The container handle is usually located on the parting surface.  

B-type cavity surface: Low inflation pressure, low molding temperature, plastic will not enter micro uneven (rough) valleys. A relatively rough surface not only does not affect the surface state of the product, but also facilitates exhaust. For products with special requirements such as high gloss and high transparency, the cavity should be polished.

C-side parting: In order to achieve uniform wall thickness for blow molded products in Shanghai, even if there are side indentations, a large slope is gradually transitioned. In addition, the demolding temperature is high and the elasticity is good, so it can be forcibly demolded without the need for side parting. For deep grooves with smaller slopes, a side parting mechanism should be installed

Clamp mouth and residual material groove

A、clamp mouth

The clamping edge is also known as the cutting edge. At the same time as the extrusion blow molding mold is closed, the remaining material needs to be cut off, so a clamping mouth should be set at the corresponding part of the mold.

B、surplus material tank

The leftover material cut by the cutting edge of the billet just falls onto the parting surface, affecting the closure of the mold. Therefore, a leftover material groove is opened at the corresponding position to accommodate the leftover material

The structural dimensions of the clamping mouth and residual material groove are the key to the design of the extrusion blow mold. In addition to cutting off excess materials, the clamping mouth also has the function of clamping and sealing the billet. If the width and angle of the clamping mouth are improper, the joint surface is not tightly fitted, and the capacity of the remaining material groove is insufficient, it may result in insufficient clamping, continuous cutting of the billet, or insufficient strength of the joint after the billet is cut.

The residual material trough is usually located on the upper and lower sides of the incision, and its size should be determined according to the width and thickness of the residual material after the billet is clamped, based on whether the mold can be tightly closed. The width of the clamping mouth is generally selected as 1-2mm, and the angle is taken as 13 ° -15 °.

The blow molding process in Suzhou includes three basic steps: preform forming, blow molding, and product cooling. First, the plastic is processed into a molded preform (injection molding or extrusion), and then the high-temperature preform is placed in a blow molding mold. Compressed air is injected into the preform to blow it tightly against the cavity wall, and the inflation pressure is maintained until the plastic part cools and sets. The process of opening the mold to obtain a hollow plastic part.

What is the specific production process of blow molded plastic products in Suzhou

Classification and characteristics of Suzhou blow molding processing technology:

According to different methods of preform preparation and blowing, there are various blow molding processes including extrusion blowing, injection blowing, extrusion pulling blowing, injection pulling blowing, etc.

1. Extrusion blow molding process - extrusion blowing

2. Extrusion stretch blow molding process - extrusion stretch blow molding

The plastic is extruded into a tubular billet through an extruder and a billet head, and the heat pipe billet is cut by a pre blown mold

And pre inflated, the pre inflated high-temperature billet is moved to the blow molding mold for stretching and inflation molding

What does Shanghai blow molding machine process? Blow molding machine is a type of plastic processing machine. After spraying the liquid plastic, use the machine to blow the wind speed to attach the plastic body in a certain shape, and then make it into a product. We can produce and process a variety of products such as plastic buckets, plastic bottles, and plastic toys.

1、 The classification of blow molding machines can be divided into two categories: extrusion blow molding and injection blow molding. The key difference between the two depends on the production of the preform, while the entire blow molding process is basically the same. The basic development trends of the two forming methods here are: extrusion drawing blow molding (commonly known as extrusion drawing blow molding), injection drawing blow molding (commonly known as injection drawing blow molding), and double-layer reflection molding.  

2、 The main purpose of blow molding machine

1）. The demand for polypropylene is gradually increasing due to the development of modified epoxy resin materials and production processing technology.  

2）. The usage of high-density high-pressure polyethylene ranks first, and it is widely used in food, chemical plants, and packaging solutions for liquids. High molecular weight high-pressure polyethylene is suitable for the production and manufacturing of large and medium-sized natural gas tanks and barrels.  

3）. Linear polyester raw materials are new materials that have entered the hollow blow molding industry in recent years. Due to its glossy appearance, high-quality transparency, high structural mechanical compressive strength, and good storage capacity for objects in containers, as well as the advantages of not polluting the environment during centralized incineration of waste, its products have developed rapidly in the field of plastic packaging bottles, especially in the application of pressure resistant plastic food packaging materials.  

4）. Polyethylene is widely used in the packaging of skincare products and detergents due to its good clarity and sealing properties. With the development and design of non-toxic polyethylene epoxy resin and modifiers, as well as the trend of Raman blow molding technology, the use of polyethylene containers in food packaging materials has rapidly increased.  

3、 Advantages of blow molding machine:

1）. Plastic containers made by blow molding machines are relatively cost-effective and can reduce living expenses.  

2）. The production and processing speed is faster and more efficient. Traditional porcelain and wooden furniture are not only time-consuming and labor-intensive, but also lack precision.  

3）. Plastic vessels produced and processed using blow molding machines have advantages such as high thickness, corrosion resistance, and wear resistance, and can replace some wood and porcelain vessels.

We hope that through this article, you have a certain understanding of blow molding machines. If you have any needs in this area, you can contact us online and we will be happy to serve you!

If you want to calculate the price of blow molding processing in Suzhou, the editor of Kunshan Juxinchang Company suggests that you first calculate the fixed cost before proceeding:

Fixed cost refers to the cost that a factory needs to incur to operate its doors, regardless of whether it is manufactured or not. This cost is measured in yuan and is calculated as: unit price/yuan/day, with three decimal places (RMB: cents).

Fixed cost calculation is only applicable to pure Suzhou blow molding processing enterprises.

If the company includes other production and manufacturing processes such as injection molding, mold processing, and finished product installation, the cost of infrastructure construction should be effectively calculated and cut.

1. Depreciation expenses for industrial plants

Existing industrial plants: total project cost ÷ thirty years ÷ 300 days

Renting industrial plants: Rent ÷ 300 days

2. Depreciation of hollow blow molding machines

Total price of mechanical equipment ÷ Ten years ÷ 300 days

3. Infrastructure construction and maintenance costs

Total annual maintenance cost ÷ 300 days

4. Maintenance cost of hollow blow molding machine

Total annual maintenance cost ÷ 300 days

5. Accounting fees

Annual attached loan interest total amount ÷ 300 days

6. Service fee

Annual total expenditure ÷ 300 days

7. Distribution of electric transformers

Annual total expenditure ÷ 300 days

8. Unforeseeable expenses

9. Other

10. Subtotal 1+2+3+... 9=X yuan/day

The calculation content and formula of Suzhou blow molding processing price show that:

Thirty years: The design service life of a general factory building is thirty years

Total Injection Capacity: The sum of the injection volumes of all hollow blow molding machines in the factory.

300 days: Calculated based on 300 reasonable working days per year.

Ten years: The service life of hollow blow molding machines and related machinery and equipment is calculated based on ten years.

When calculating the price of blow molding processing in Suzhou, there are still many factors to consider. However, the editor of Kunshan Juxinchang Company will talk about so much today. Many other contents, including variable costs, will be shared and discussed with you next time. Everyone should digest and absorb today's professional knowledge.

Multi layer blow molding is a Suzhou blow molding processing technology developed to meet the special requirements of packaging containers such as airtightness and corrosion resistance in certain industries such as pharmaceuticals, food, and cosmetics. Its basic process principles are the same as those of single-layer product blow molding technology, mainly including co extrusion blow molding and injection molding blow molding.

When using co extrusion method, multiple extrusion sails are used to simultaneously squeeze different resins into multi-layer machine heads to form multi-layer concentric product preforms, which are then blow molded. When using injection molding for blow molding. Then, a layer is first injected onto the male mold, and the mold cavity is changed to inject on the first layer to form the second layer. This process is repeated to form a multi-layer product blank, followed by blow molding. Multilayer systems that have been adopted in industry include polyamide/polyolefin, polystyrene/polyacrylonitrile/polypropylene, polyolefin/polyvinyl chloride, etc

Multi layer blow molding is a technology that uses two or more extruders to melt and mix the same or different types of plastics in different extruders, then composite and extrude them in the same head, and blow mold to manufacture multi-layer hollow containers.

Suzhou multi-layer blow molding processing is developed on the basis of injection molding blow molding and extrusion blow molding, with little difference in process, except that the product wall is not a single layer but multiple layers. The multi-layer structures used include nylon/polyolefin, polyvinyl alcohol/polyolefin, polyethylene/polyvinyl chloride/polyethylene, polystyrene/polyacrylonitrile/polypropylene, etc.

Multi layer blow molded containers are mainly designed to meet the increasing demand for airtightness in cosmetics, pharmaceuticals, and food packaging. Therefore, the raw materials and layers of multi-layer containers should be selected according to the needs. Two types of plastic two-layer structures, two types of plastic three-layer structures, three types of plastic four layer structures, or four types of plastic four layer structures can be used. The more levels there are, the higher the technical requirements.

The key to multi-layer blow molding is to control the fusion bonding between the resin layers, and there are two bonding methods. The first method is to mix resin with adhesive properties, which can reduce the number of layers while maintaining a certain strength. The second method is to add a layer of adhesive material, which requires the purchase of an extruder for extruding the adhesive material, making the equipment and operation more complex.

Suzhou multi-layer blow molding is a process of directly blowing or stretching multi-layer preforms to form multi-layer hollow containers. Multi layer preforms are co extruded by multiple extruders and then blow molded, known as co extrusion blow molding; If a multi-layer billet is formed by injection molding and then blown, it is called co injection blow molding.

The use of multi-layer composite technology is usually based on the following considerations:

(1) By placing a small amount of resin with excellent barrier properties but high cost in the middle layer of a multi-layer structure, the barrier performance of the container can be improved and the shelf life can be extended at a relatively low cost.

(2) Recycling resources and reducing costs. For example, recycled materials can be placed in the middle layer, or a layer of resin mixed with expensive colorants or UV resistant materials can be placed on the outer layer to reduce costs.

(3) Other functional needs. Including optical effects, tactile effects, and usage effects generated by the combination of materials with different properties.

In short, the ultimate goal of multi-layer composite is to optimize the combination of different functional materials, complement each other's strengths and weaknesses, and enhance the value of the product. The materials used include the same type of material, as well as materials with significant differences in chemical structure. In the latter case, an adhesive is required to increase the interlayer bonding force. However, significant differences in the rheological behavior of different materials will increase the difficulty of the process.

The typical application of multi-layer blow molded products in Suzhou is the packaging of milk, natural fruit juice, tea drinks, tomato sauce, carbonated soft drinks, beer, seasonings, and cosmetics that require high barrier performance.

Generally, various problems are prone to occur during the blow molding process of products, such as blown glass bottles, bottom end aggregation, bottom end skewness, thin bottle body, and glass bottle whitening. How to distinguish between blowing problems and bottle preform problems. Now everyone is analyzing the different situations blown out of the glass bottle;

1、 Reason for glass bottle breakage:

1）. Insufficient heating of embryo tubes, not fully baked;  

2）. The Rashin pole was not pulled in time (exactly);  

3）. Rashen rod speed is very slow;  

4）. The temperature protection has been turned on, but the upper and lower temperature limits have been set too high.  

2、 Solutions to common faults in blow molding products:

1）. Widen the working voltage without changing the production volume. Reduce production without changing the working voltage, which means extending the time for secondary blowing inspection.  

2）. After locking the exhaust pipe, use force to push the pull rod down and touch the bottom of the mold, and tighten the limit switch nut. (Limited to cylinder adjustment for mechanical equipment only).  

3）. Adjust the relief valve on the Rashin cylinder to a larger size.  

4）. Lower the lower temperature limit. Generally, PET preforms are set to 85-95 degrees, and the limit can be set to 125-130 degrees. That's all for the general faults in blow molding processing. We hope it can be helpful to everyone. If you have any needs in this area, you can consult us online and we will be dedicated to serving you!
