How to avoid mold jamming and product deformation of plastic molds?

The mold opening process of plastic mold is a key link in the production of plastic products, which has an important impact on the life of the mold and the quality of the product. Mold jamming and product deformation are common mold opening problems, which can lead to low production efficiency and reduced product quality. In order to ensure smooth mold opening and high-quality products, a series of measures must be taken to avoid mold jamming and product deformation. This article will introduce how to avoid mold jamming and product deformation during the mold opening process of plastic molds, and provide some practical methods and tips.

1. Methods and techniques to avoid mold jamming:

1. Reasonable selection of mold materials: select the appropriate mold materials to ensure the hardness and wear resistance of the mold. Reasonable selection of mold materials can reduce the friction coefficient of the mold surface and reduce the possibility of mold jamming.

2. Proper processing and treatment of the mold surface: Through proper processing and treatment, the finish and lubricity of the mold surface are improved. Polishing, EDM and other methods can be used to reduce the roughness of the mold surface and improve the lubricity of the mold.

Reasonable design of mold structure: reasonable design of the structure and shape of the mold to ensure the smooth opening of the mold. Consider the shape and size of the product, and avoid overly complex mold structures and overly tight fits.

2. Methods and techniques to avoid product deformation:

1. Reasonable selection of plastic materials: choose the right plastic materials, and choose the appropriate melting temperature and fluidity according to the requirements and shape of the product. Reasonable selection of plastic materials can reduce the thermal stress and deformation of products.

2. Control the injection parameters: reasonably control the injection parameters, including the injection temperature, injection pressure, injection speed, etc. By adjusting the injection parameters, ensure that the plastic material fully fills the mold cavity and reduce the deformation of the product.

3. Reasonable design of product structure: Reasonable design of the structure and shape of the product to reduce the possibility of stress concentration and deformation of the product. Consider the shape and size of your product and avoid overly thin-walled, long-striped, and sharp parts.

Avoiding mold jamming and product deformation is the key to ensure product quality and production efficiency during the mold opening process of Fanshida plastic mold. The occurrence of mold jamming can be avoided through reasonable selection of mold materials, appropriate processing and treatment of mold surface, reasonable design of mold structure, control of mold temperature and use of appropriate mold lubricants.
