Plastic mold is a tool used in the plastic processing industry to match plastic molding machines, giving plastic products a perfect configuration and precise dimensions. Because the variety of plastics and processing methods are complex, and the structures of plastic molding machines and plastic products are complicated, the types and structures of plastic molds are also diverse. So, what are the general requirements for the processing of plastic molds? Let us briefly understand.
1. High production accuracy. In order to produce qualified products and give play to the skills of plastic molds, the planning and production of plastic molds must require high precision. The accuracy of plastic molds is mainly determined by the accuracy requirements of the products and the structure of the molds. In order to ensure the accuracy and quality of the materials, the accuracy of the working parts of the plastic molds is generally 2 to 4 levels higher than the accuracy of the products. The plastic mold structure has higher requirements for the cooperation between the upper and lower molds. The parts that make up the plastic mold must have sufficient manufacturing accuracy, otherwise the plastic mold may not produce qualified products and even lead to plastic The mold cannot be used normally.
2. Long service life. Plastic molds are relatively expensive process equipment. At present, the production cost of plastic molds accounts for about 10% to 30% of the product cost. Its service life will directly affect the production cost. Therefore, except for special cases such as small batch production and trial production of new products, plastic molds are generally required to have a longer service life. In the case of mass production, the service life of plastic molds is more important.
3. Short production cycle. The length of the plastic mold production cycle is mainly determined by the level of production skills and production management. In order to meet the production needs and improve the competitiveness of products, it is necessary to shorten the production cycle of plastic molds as much as possible on the premise of ensuring quality.
4. Low production cost. The cost of plastic molds is related to the degree of clutter of the mold structure, mold materials, manufacturing accuracy requirements, and processing methods. Plastic mold planners must rationally plan and formulate their processing technology in accordance with product requirements, and try their best to reduce mold manufacturing costs.
