Precision injection mold manufacturer

Precision mold design and plastic injection mold manufacturing Before injection molding, mold processing manufacturers need to go through a detailed mold production design process. In recent years, the requirements for precision mold design have become increasingly higher. When designing molds, plastic injection mold manufacturers must use automated design programming and supporting tools to improve the precision and accuracy of the design process to meet the strict requirements of modern enterprises for injection mold precision.

The use of precision injection mold processing can not only effectively ensure the quality of plastic products, but also significantly reduce production costs. Mass production through precision injection molds can achieve an efficient and high-quality production process.

Precision injection mold design process

The design process of precision injection molds mainly relies on computer automation programming systems to assist in the preliminary design of the mold. After the design is completed, the mold data is processed to form an efficient operation mode. This process includes the precise layout of the mold by benchwork, followed by processing the inserts, and cooling with the help of the pouring system. The entire design and production process of precision injection molds ensures orderly operation under specified conditions, thereby ensuring the production and operation efficiency of the mold.

When mold processing manufacturers consider precision, processing speed and quality requirements, the design of precision injection molds is particularly important. When designing the mold, the specific cavity shape is closely combined with the injection mechanism of the plastic, which can effectively complete the replication and processing of the injection molded parts. Compared with traditional molds, products processed by precision injection molds are not only more precise, but also more stable in finished product quality.

Mold structure and cooling system

Precision injection molds refer to products with specific shapes obtained after injecting resin materials into metal models. In mold design,  plastic injection mold manufacturers will set cooling holes and heaters on the mold to control the temperature during mold operation. The molten material is injected into the mold cavity through the main channel and the branch channel. After cooling, the mold is opened and the ejector on the molding machine will push the product out.

The molded product includes the structure of the molten resin entering the main channel, the branch channel and the mold cavity. Usually, injection molding manufacturers will design the length of the branch channel to be equal to ensure uniform distribution of the fluid. In addition, the use of return materials in the main channel and the branch channel is also very critical. These recycled materials are not used as molding materials alone, but are mixed with new materials and reused. This is because the resin after one molding will change in mechanical properties, fluidity, color, etc.

In summary, plastic injection mold manufacturers should not only pay attention to design and processing accuracy, but also focus on production efficiency and rational use of materials to meet the growing market demand.
