Casting plastic molds should have strict standard tolerance requirements

In the manufacturing process of casting plastic molds, scientific researchers must have strict operating standards when determining the tolerance standards of casting plastic molds. When designing plastic molds, they must conduct specific investigation and analysis according to the application field of plastic molds. , Collect relevant data about plastic molds, production operation skills and precautions for production molds in advance, and make plastic molds according to the requirements of different industries for casting plastic molds. The inspection organization of plastic molds must set up strict inspection standards. After that, relevant technical personnel must calibrate the plastic mold products. Before casting the plastic mold for production, a production test must be carried out to determine that the product produced by the plastic mold meets the production practice before mass production of the product.

Fully consider the shrinkage of the casting plastic mold

In view of the fact that the shrinkage rate of cast plastic molds is susceptible to conditions, researchers should fully consider the shrinkage coefficient of plastic molds when making cast plastic molds, and adjust the shrinkage range of the mold according to the production location and industry of the cast plastic mold. Different plastic mould schemes are formulated for the products of the company. In some production practices with strict requirements, the moulding and calibration of cast plastic moulds can be calibrated by combining wood or metal moulds. The changes in environmental conditions are fully considered to improve The precision of the plastic mold, and at the same time, the high temperature and pressure resistant matching materials can be added to the cast plastic mold material during the processing of the cast plastic mold to reduce the shrinkage rate of the plastic mold and make the produced product more adaptable to the more complex environment .

Improved production method and accuracy

Casting plastic molds in the traditional manufacturing and shaping mode are far from being able to meet the needs of the current development of plastic molds, and one of the mold making methods developed to meet the current production needs, but in order to adapt to the rapid development of technology and industry in the production of plastic molds In the process, it is necessary to continuously innovate production methods, add new innovative methods, and combine traditional casting methods with equipment digital program control operations. This will not only save materials to the greatest extent, but most importantly ensure the high accuracy of plastic molds. Effectively improve the accuracy of the plastic mold, so that the coverage rate of mold standard parts and the rate of mold commercialization have been greatly improved, and the proportion of hot runner molds has also been greatly improved.
