Kids chair plastic mold steel selection
In the selection of chair mold steel, such products are of higher requirements for appearance, and the surface of the product requires high brightness. Therefore, the choice of mold material is not important, it is not to say that the higher the price, the better. Different products have different requirements for steel. Most of our recommendations are: P20, 718, 2738, 2316, NAK80, S136, H13, etc. It is best to use P20 and 718 for the chair mold if no special requirements. The price of the product is reasonable. It can also make the surface of the product reach a certain degree of finish. The internal requirements are high, especially the gears adopt 2316 and NAK80.
How to check if the chair mold is qualified?
After the chair mold product is formed, we need to check the superimposed effect of the chair, such as stacking the verticality if it is straight, stacking 15 layers.
2. Gram weight:
The general big chair is 2.2kg. Overweight will increase the cost of the customer and cause loss of profits. If it is too light, the wall thickness will be reduced and the quality of the product will not meet the standard.
Consider the possibility of deformation between the chair frame and the four legs. Generally, we test the use of one hundred kilograms of material instead of manual, stacking for 24 hours, and the deformation distance between the four legs can not exceed 3 cm.
4. Is the parting line sharp?
It is dangerous to have a rough parting line on the chair. It is easy to scratch the skin of women and children and must avoid sharp edges in mold.
