As a household product mould , we will pay special attention when buying, because most users are family members or friends with good relationships, so we will purchase household molds more strictly, but no matter how strict, we will not stop us. We don't know how to choose. So what should you pay attention to when choosing a household mold?
The first is corrosion resistance. When some molds (such as plastic molds) are in operation, due to the presence of chlorine and fluorine in the plastic, they will separate and analyze strong corrosive gases (such as HCl and HF) after heating. These corrosive gases will corrode the surface cavities. And increase its surface roughness and increase the wear failure rate.
The second is the process performance requirements of household product molds. Mold manufacturing usually requires several processes, such as forging, cutting and heat treatment. In order to ensure the quality of mold manufacturing and reduce production costs, the material should have good forgeability, machinability, hardenability, hardenability and grindability; it should also have small oxidation, decarburization sensitivity and quenching Deformation and cracking tendency.
Finally, of course, the price. When selecting mold materials, economic principles must be considered to reduce manufacturing costs as much as possible. Therefore, under the premise of satisfying the performance, first choose a lower price, carbon steel may not use alloy steel, and domestic materials may not use imported materials.
Regardless of whether it is plastic chair injection mould or which mold is used, it should be noted that the mold should be installed stably, the mold joints should be firm, leak-proof, and easy to disassemble. At the same time, attention must be paid to the cleanliness of the mold, the geometric shape support of the template must have sufficient strength, rigidity and stability, and the connection between the inlet and outlet and the dome or dome must be considered. When using bricks as internal molds, please note that the inside of the bricks should be damp and the outside should be dry.
