Some mold steel such as H13, 2316, S136, etc. can be done vacuum quenching harding treatment to make the hardness 48-52HRC. In order to get the long mold life.
The hardening treatment need to be done after mold rough tooling before detail tooling. Due to after treatment, the steel hardness is very high, so the tooling time is long. This is the reason that mould made with steel which hardness required 48 to 52hrc, the mould test time is longer than other steel mould (for example P20 steel).
XS Plastic Mould Co., Ltd is a professional plastic mould factory, we have rich experince in making plastic chair mould. We just tested a chair mould yesterday. Welcome to contact us for the plastic chair mould.
Injection molding is a common method for mass production and is often preferred over other processes, given its capability to economically make complex parts to tight tolerances. Before any parts can be molded, however, a suitable injection mold must be designed, manufactured, and commissioned.
The mold design directly determines the molded part quality and molding pro- ductivity. The injection mold is itself a complex system comprised of multiple com- ponents that are subjected to many cycles of temperature and stress. There are often tradeoffs in mold design, with lower-cost molds sometimes resulting in lower product quality or inefficient molding processes. Engineers should strive to design injection molds that are “fit for purpose”, which means that the mold should pro- duce parts of acceptable quality with minimal life cycle cost while taking a mini- mum amount of time, money, and risk to develop.
In the beginning of mould design, enginner need to analysis the part design, wall thickness, part material, etc. to get right idea on the gate position, gate size, hot runner or cold runner, sliders position and slide direction, and other mould structure.
Reasonable mould sizes can insure the mould quality, and make sure the designed mould fit client pointed injection molding machine. We should avolid to make the mold with unreasonable small size just in order to make the mould fit the injection machine, as such mould strength is very week, mould life will be short.
An injection mold has many structures to accomplish the functions required by the injection molding process. All the mould parts should be with good design, and then they can be tooled with good structure and running smoothly on the mould during injection moulding. A bad mould design is a beginning of bad mould or even result a failture mould.
XS Plastic Mould Co., Ltd put the mold design on the high level, and tool the moulds all acording the 3D data to make sure the mould with high quality.
