Metal injection molding mold design MIM

MIM (metal injection molding) mold design is not a simple task, tolerance and strict, need to pay special attention to the details of the complex, all this is like climbing to the peak of an iceberg, very difficult.

High precision, super high tolerance without flash, surface quality, all of these standards are some requirements must meet the manufacturing process of metal parts die casting die. There is no doubt that the metal mold manufacturers to reach this level although there are a few, but very few, however, for this industry companies, is "profitable".

First of all, the mold design should have a good plan. Shenzhen ZCMIM company's engineers had pointed out, "because it is the foundation and the key to success. It should include excellent cooling water circuit layout and parting line lock locking device, to prevent the dislocation of production and processing of mould, a deputy to good support of mould cavity and core sidewall mold frame, a suitable for specific parts demoulding method. "

The basic structure and the injection mold MIM mold is similar, only a few exceptions. Including steel mould cavity and core, close the angle with the selection of member and the slider, materials with good liquidity of the runner system design, gate location, ventilation depth, molding shaping region of the surface quality and its applications in coating mould cavity and core details correct choice. " Our company engineer told Xiao Bian, and detailed these views. Because of the many mold manufacturers according to the general design began to manufacture the mold, so when the mold manufacturing, machinery and tooling division they give workers many degrees of freedom design details. But this method of MIM mold manufacturing is invalid.

MIM molding mold manufacturers and workers not to observe a mold layout, their main task is to study and observe a set of detailed drawings. They spend more time in front of mold design details, so the successful operation of the mold to obtain the spent less time. The details of the design, including the selection of die materials and mould cavity tolerances, surface quality and coating, gate and runner size, vent position and size, position of pressure sensor. After the successful production of MIM mould, demoulding and cooling has become a key problem.
