Look, this hardworking and conscientious woman, why was she punished? Look, this hardworking and conscientious woman, why was she punished?Yes, she didn't wear protective goggles. She violated the work regulations.
The specific steps of the anodizing process include The specific steps of the anodizing process include:
1 Preliminary treatment:
polishing and chemical treatment of aluminum or aluminum alloy products to remove oil, fingerprints and other impurities on the surface of the product.

When the metal liquid passes through the gate, its filling method can be divided into three ways: layer flow filling, jet flow filling and atomizing flow filling. When the gate speed is low, the filling mode shows laminar flow. When the speed increases, the liquid metal is no longer a continuous outflow, but a coarse granular ejecta; At higher speeds, the water bursts out in a mist of fine particles. Laminar flow filling or mist flow filling can produce satisfactory castings, but coarse particle flow filling is not good because of the heat loss in the filling process.
The cooling system of plastic mold is so important? First of all, the design of the cooling system is crucial to the molding cycle of the plastic product.
During the plastic molding process, the thermoplastic needs to be cooled and hardened in the mold cavity so that it remains solid and has enough strength to be removed. If the cooling time is too long, it will lead to low production efficiency; On the contrary, the cooling time is too short, which will lead to local shrinkage or deformation of plastic products.
Why in the plastic mold injection production must pay attention to exh First, the principle of plastic mold exhaust actionIn the injection molding production of plastic molds, exhaust treatment is required. The exhaust function refers to the removal of the accumulated gas in the mold cavity to prevent the occurrence of defects such as bubbles. In the molten state, the plastic is injected into the mold, and there is a certain amount of air in the mold cavity. If there is no exhaust treatment, the air can not be completely eliminated, will form bubbles, affecting the quality of molding.
