Metal Injection Shock Absorber Parts

Metal injection molding(http://www.zcmim.com/) is used in industrials and electronics. It is also being applied to automatic absorber parts, motorcycle shock absorber, piston rod and piston guide valve such kind important components. Considering the stable damping force of shock absorber, powder metallurgy part has high precision sheet surface, can reduce friction and guarantee the stability of operation, improving comfort as well.

Characteristics of Metal Powder Metallurgy

metal powder metallurgy

characteristics of metal powder metallurgy(http://www.zcmim.com/):
1. Product density is controllable, such as porous materials, good density material, etc.;
2. Grain fine and uniform microstructure, no composition segregation;
3. Net shape forming, the utilization rate of raw materials > 95%;
5. Less cutting, cutting only 40 ~ 50%;
5. Composition of materials is controllable, applying composite materials;
6. Preparing refractory metals, ceramic materials and nuclear materials.

Mobile Phone Processing Technology In 2017

Since the appearance of Xiaomi 5 ceramic glass shell in 2016, it brands new image of mobile phone. there is also news that iphone8 will use stainless steel and composite materials to explain a new generation of mobile phone shell. From process, the industry mostly used many milling to machine blank into shape, namely the so-called integrated molding technology. Through CNC, injection molding, polishing,grinding and anodic oxidation treatment can finish manufacture. In addition, stamping and die casting process are also used among them. Although metal injection molding (injection molding and metal injection molding) shorten production cycle, saving materials and reducing cost, but some bubbles happened in injection and uneven cooling question when melt combined with mould needs to be improved. Whether mobile phone processing technology stand out from the competitionin 2017, we look forward to it!

Plasticizing Pressure Control in Metal Injection Molding

Plasticizing pressure in metal injection molding(http://www.zcmim.com/) refers to the back pressure when adopting screw injection machine, the molten material in screw top beared when rotate back. The size of pressure can be adjusted by overflow valve of hydraulic system. During injection, the size of plasticizing pressure changed along with screw rotation speed. Increasing plasticizing pressure will raise the temperature of solution, but will reduce plasticizing speed.

Temperature Effect on Metal Injection Molding

Mold temperature has great impact on product’s  inner performance and quality in metal injection molding process(http://www.zcmim.com/manufactureequipment.shtml). Mold temperature is determined by the crystallinity of plastic, product dimension and structure, performance requirements, and other process conditions (melt temperature, injection speed and injection pressure, molding cycle, etc.).

the MIM process cooling time

The MIM process(http://www.zcmim.com/helps/mimprocess.html) cooling time (4 to 7) when the melt into the cavity, touching the metal surface, melt cooling step is already started.Because of polyformaldehyde, nylon, and polyethylene semicrystalline materials such as carbon solidification temperature is very high, so little time to cooling.If the general module, after completion of the melt, the module should have enough cooling time.If you find a problem when ejection module, can extend the cooling time, slowly until problem solving.

metal injection molding mould opening time

Metal injection molding mould(http://www.zcmim.com/help/leaveword.shtml) (8-11) mold opening time is an important part of the whole cycle, especially to have insert mold especially, even in relatively standard mold, mold opening time is often higher than 20% of the whole cycle.
