High Quality gas assistant chairs molds Suppliers:When the ejection is not completely cooled, the ejection force of the ejector rod often causes the deformation of the molded parts, so the deformation occurs when the ejector is not completely cooled. The countermeasure is to cool fully in the mold cavity and eject after full quenching.

can reduce the mold temperature, extend the cooling time. However, some of the mold local cooling is insufficient, in the normal molding conditions can not prevent deformation.
In this case, consideration should be given to changing the path of the cooling water, the position of the cooling water channel or increasing the cooling pin hole, in particular the use of air-cooled instead of cooling. The demoulding performance of some parts is poor, which is caused by the deformation caused by the forced demoulding of the top rod. For plastic structures that are not easy to deform, they produce cracks rather than deformations.
For ABS and polystyrene components, this deformation causes tables and chairs to be molded. The surface of the product is whitened according to the driving position (refers to cracking, cracking, microcracks, whitening). The elimination method is to improve the polishing quality of the mold, so that the mold is easy to demoulding. Sometimes release agents can also be used to improve the demoulding effect. The most fundamental improvement method is to grind the core, reduce the demoulding resistance, or increase the inclination of the drawing die, in the area where it is not easy to eject, increase the ejector rod, more importantly, change the ejection mode.
