What is foam mold?

Foam molding mold is a plastic foam mold (English: foaming mould). Foaming resin is directly filled into the mold, so that it is heated and melted to form a gas-liquid saturated solution. Through nucleation, a large number of tiny bubble nuclei are formed, and the bubble nuclei grow to make foam plastic parts. The die head has a streamlined flow channel surface, two half die body design, the die head disassembly, cleaning is simple and easy. Manually fine-tune the elastic die lip or movable upper die lip design to suit the different thickness requirements of the extruded sheet. Vertical or oblique 45¡ã choke rod design to adapt to different viscosity of molten material flow uniform distribution. The die body is made of high quality die steel or imported alloy steel to extend the life of the die.

Advantages of foam mold

1, foam mold has the advantage of lightweight

Products manufactured by foaming molds have a lower body weight, greatly reducing the amount of material used. This not only saves costs, but also reduces the burden during product use.

2, foam mold has excellent thermal insulation performance

The air foam cell structure in the foam mold product can effectively prevent the conduction of heat and play a good thermal insulation effect. Not only can reduce energy consumption, but also provide a more comfortable use experience.

3, foam mold also has good shock absorption function

The foam hole structure in the mold can absorb external impact forces, reducing the risk of product damage and breakage. This plays an important role in areas such as automobiles, electronics and displays

4, foam mold production efficiency and cost effectiveness is also one of its advantages.

The manufacturing process of the foam mold is relatively simple, and the injection molding foam technology can achieve mass production. Compared with traditional metal molds, foam molds have lower costs and shorter production cycles. This allows manufacturers to launch products faster and meet market demand.

Foam molding mold design steps

1. Product design

First of all, product design needs to be carried out according to the shape, size and functional requirements of the product. Determine the shape, internal structure and special requirements of the product.

2. Mold design

According to the requirements of product design, carry out mold design. Mold design needs to consider the shape, size, wall thickness, structure and other factors of the product to ensure that the final product meets the requirements.

3, mold production

According to the mold design drawing, make the mold.

4. Material preparation

Select suitable mold materials, such as aluminum alloy, steel, etc., and carry out material cutting and processing.

5, processing and production

According to the mold design drawings, mold processing, including milling, drilling, turning and other processes.

6. Assembly and debugging

The machined mold parts are assembled, and debugging and testing are carried out to ensure the normal operation and forming effect of the mold.

7. Mold debugging

After the completion of mold production, it is necessary to carry out mold debugging. Through mold testing and adjustment, ensure that the mold can be normal injection molding and molding, and meet the quality requirements of the product.

8. Prenatal verification

Pre-production verification is carried out before formal production. Through the production of a certain number of samples, inspection and testing, to ensure that the quality and performance of the product meet the requirements.

9. Mold maintenance

In the production process, it is necessary to carry out regular maintenance and maintenance of the mold, including cleaning, lubrication, repair, etc., to extend the service life of the mold and ensure the stability of production.

Guangzhou OTEM Engineering Plastics Co., Ltd. has more than 20 years of foaming mold, hot runner mold, cold runner mold processing experience, with more than 2,000 square meters of physical plant, as well as professional production equipment and design team, can provide you with professional and satisfactory product services!

Precautions for foaming mold

1. Be sure to sharpen the knife edge after long-term use of the mold, and be sure to demagnetize the knife edge surface after grinding, and do not contain magnetic force, otherwise it is easy to block the material.

2, spring and other elastic parts in the use of the spring is the most vulnerable to damage, usually rupture and deformation conditions. In the replacement process, we must pay attention to the size specifications and product models of the spring, the size specifications and product models of the spring are determined according to the color, outside diameter and length, and can only be replaced if they are consistent.

3. The punching needle is prone to fracture, bending and gnawing in the use of the mold, and the punching sleeve is usually gnawing. Damage to the punch needle and punch sleeve is usually replaced with parts of the same size specification. The basic parameters of the punching needle include the size specification of the working part, the size specification of the installation part, and the length and length of the size specification.

4, fastening parts, routine check whether the fastening parts are loose, damaged, the way is to find the same size specifications of the parts to replace.

5, roll parts such as roll plate, good force glue, etc., pour parts such as stripper plate, pneumatic top, etc. During maintenance, routine inspection of the relationship between parts and accessories in each position and whether there is damage, repair the damaged parts, routine inspection of air leakage, and take measures for specific situations. Replace if trachea is damaged.
