How does NJPE precision mould prevent heat treatment deformation?

by:NJPE     2020-02-09
NJPE has done pre-deformation treatment for customers in the early stage of precision mold production, especially for baby carriage injection molds, which requires extremely high part difference and requires tolerance to remain at 0. Within 03mm, and the baby carriage mold products are mostly deep cavities, which are prone to deformation in the production process. Therefore, it is particularly important to prevent heat treatment and deformation of precision molds for customers. It can effectively improve the qualified rate of moulds and save the processing cost of precision moulds for customers. How does NJPE precision mould prevent heat treatment deformation? Generally, there are the following technological methods: 1. Hole blocking method; 2. Hole binding method; 3. Mechanical fixing method; 4. Suitable heating method; 5. Accurately select the cooling direction of the mold; 6. Accurately select the direction of motion in the cooling medium. Reasonable tempering heat treatment process can effectively reduce the deformation of precision complex molds. Often precision and complex molds are more prone to deformation problems. At this time, it is particularly important to select reasonable mold materials. Select die steel (Such as air quenched steel) For different die steel, the best heat treatment method should be scientifically adopted when casting dies. Pre-heat treatment before machining can effectively eliminate a large amount of residual stress generated during machining. In the heating process, the heating temperature should be reasonably selected, the heating speed should be mainly controlled, and the slow heating method, preheating method and other balanced heating methods should be adopted to minimize the deformation of the mold during heat treatment. Of course, some heat treatment processes introduced above can also be adopted to minimize the deformation of precision and complex molds. In addition, the structural design of precision molds is also particularly important. Scientific and reasonable first, the thickness of different surfaces should avoid too much disparity. For molds with large shape changes and asymmetry, the deformation law of precision molds should be grasped, reserve machining allowance. At the same time, for large and precise complex molds such as automobiles, a combined structure can be used to minimize the risk of deformation.
