Plastic Injection Molding Thick Parts

Product Details

We can carry out high-speed injection molding, foam injection molding, vacuum injection molding, and layered injection molding to cope with different wall thickness and efficiency requirements. The choice of materials depends on the way your product is used, such as where the product you make is used, high-temperature resistance, or non-toxic. This is the standard for material selection. Because what material you choose depends on your performance requirements. The shrinkage is related to the processing technology. If the performance requirements are not very high, but the molding is only considered, the modified polypropylene can be selected, which is more cost-effective. For example, filled or reinforced polypropylene, etc., we will give you the best solution to match the materials in the use environment of the parts we need.

Parameter of Plastic Injection Molding Thick Parts

Uniform wall thickness is one of the key factors for the reasonable design of plastic parts, which is very important to ensure product quality and smooth processing. At the same time, pay attention to the recommended wall thickness of different materials in the design. The recommended wall thickness of thermoplastic injection products
Keeping the product wall thickness consistent can avoid problems during filling and packaging, and help reduce the internal stress of the material. Generally, stiffeners can be used to reduce the thickness of the profile, increase the rigidity and strength of the product, and provide flow space for the product cavity. The ribs should be placed as far as possible in the direction of material flow, which helps to reduce the fusion line and pressure drop during mold filling. Minimum wall thickness for insert molding.
With the development of the electronic information industry and the development of various consumer electronic product markets, the application of various plug-in molding continues to expand. When molding the insert, the minimum wall thickness of the corresponding plastic is required.
For example, when a screw hole assembled by a detachable screw is pre-formed on the part, it is necessary to pre-install the insert in the mold during the molding process. The bottom of the corresponding threaded hole has a minimum wall thickness requirement. When using high shrinkage resin, the blade should be smooth and without sharp corners, clean and preheated. This will reduce the stress around the blade and eliminate the possibility of stress cracking during use. All designed product assembly should be injection molded and tested to ensure that these products can meet the requirements in actual use.
