PC parts injection technology is good or not which play a important role in PC parts production, so we pay more attention to PC parts injection notice, especially in injection machine selection, injection moulds design points.
The injected PC parts are with high transparency, high gloss, and widely used in electric cover parts and inner structural parts. Below are the PC parts injection notice.
PC parts injection specification:
Before injection, the PC material needs to be dried for at least 4 hours. Pure PC drying temperature is 120℃,and for modified PC, is110℃. All PC materials can be dried more than 10 hours.
PC parts mould design point:
PC parts mould temperature is about 80℃ to 100 ℃, if adding glass fiber, the temperature is about 100℃ to 130 ℃. Like some small products, the pin gate can be used, and the gate depth needs to be 70% of most thick position. The flowability of PC is not good, so the gate is bigger, will be better, and the runner should be short and round, venting slot should be 0.03-0.06mm, the demoulding angel be about 30′-1.
Injection machine suggestion for PC parts injection:
Now PC products, due to cost and other reasons, almost use the multi-purpose modified materials, especially the electric products, still must increase the fireproof performance, by the flame retardant. In the PC injection molding, the requirement for injection molding machine of plasticizing system are well mixed, corrosion resistance, the conventional plasticizing screws hard is meet the demands, when the choose and buy the injection molding machine, be sure to explain in advance. Dakumar Machiney has a dedicated PC screw for the customer to choose.

But how to do ability to reduce the cycle time of injection mold? In accordance with the following steps can reduce the cycle time of injection mold and injection molding has become more efficient.

1, using the high-speed injection molding machine injection molding machine injection molding steps have melt plastic, injection molding, open mold, mold closing and ejection products etc. Injection molding machine itself function is one of the main factor affecting the injection molding cycle time, high-speed injection molding machine has many advantages in terms of speed.

2, ensure that the mould structure simple and understand, in other words is to make the mould design difficulty is lower as much as possible. Most of the mold can use different methods to carry on the design, and mold release can also have a variety of ways. Simplify the mold design can reduce the cycle time of injection mold.

3, for the plastic mold used the best cooling system, use cold water to mold for cooling, in addition to mold injection molding takes time, the cycle of cooling also accounted for a lot of time. So, the use of low temperature cooling water and cooling water through the cooling system very quickly help to reduce the cycle time of injection mold.

Above three points are the main factors that influence the cycle time of injection mold, optimizing these factors can reduce the cycle time of injection mold, decreases the cost of production. If you want to learn more about injection molding cycle time, please contact us.

During the plastics melting, plasticizing process, melted materials constantly move toward the barrel front-end (measuring chamber), and more and more, and gradually formed a pressure to promote screw back. In order to prevent the screw back too quickly, to ensure melted material uniform and compacted, you need to give a opposite pressure to screw this opposite directional pressure is called injection machine backpressure.
Injection machine backpressure, also known as the plasticizing pressure, it is controlled is by oil return throttle of injection molding machine cylinder.
Reasonable adjustment for the injection machine backpressure can increase the stablability of injection volume and production dimension, reduce the water gas in the plasticized materials and improve the injection defects, like deformation, sink mark, welding lines.
If you want to know more about injection machine backpressure, or want to know how to use injection machine backpressure advantages, pls contact Dakumar.

Many customer want to get the long life plastic machine and they always want to get the injection machine from supplier is guarantee with long life, but the long life also need yourself protective.

1．First suggestion to make long life plastic machine.The additional material like GF and mental powder will cause the screw wear and tear, in order to increase the screw life, we should properly increase the temperature and reduce the screw speed rate, or chroming.

2．Second suggestion to make long life plastic machine.Avoiding long time running the plastic machine in the high speed and high pressure condition.

3．Third suggestion to make long life plastic machine.Some mistakes could cause by the human factor, like put the wrong plastic material, which material need the high temperature, but the barrel have not reach the high temperature, so it need much power from the screw, so it will make the screw break off.

4．Forth suggestion to make long life plastic machine.All the plastic material heating will resolve acidity gas. And the material is easy stick to the mould, so we had better choose stainless steel machine parts and by the way ,in the technology ,we should use the low back pressure and low temperature, so that it can reduce the plastic material degradation.
