Valve gate hot runner systen widely used in making products with high precision, such as instrument panel, bumper, household appliances, automobile and motorcycle accessories, etc. Since the it have many advantages to promise the quality of the goods. Here i want to show you some benefits of valve gate hot runner .

Valve gate hot runner wins more and more honor among the customer since it has five main special features . First , products surface have no gate mark, so it is suitable for processing fine surface. Second, there are valve needle in the inner side, needle valve controled by the pneumatic or hydraulic . Third , timing control, switching can be controlled punctuality. Fourth, good sealing performance, products with smooth surface with valve gate system and also the speed is faster. Fifth, sutiable goods with high precision since the plastic flowing condition is well in this system. Here are the main benefits of valve gate hot runner .

If you are interested in or want to know anything about valve gate hot runner system or hot runner system . Please feel free to contact me

nice injection gate for mouldt|he most importance fluence for nice injection gate|Sino Mould

Nice injection gate is the important issue for the preform mould. Gate mark too long is the main issue that influenced the preform. To solve this issue we check out the reasons and also get the solution from them . Here are the solution ensure the Preform mould nice injection gate

Long gate mark means the preform have too long raw material. Probably reasons can be divided into four parts. The first cause is that the injection gate is too cold when the valve is closed. To avoid this matter, we should first increase the injection nozzle temperature. And also we longer the valve injection time.

The second reason is that the valve abnormally close. When facing this issue, we should do the follows.

1. Increase the mould sub runner temperature.
2. Check whether the hydraulic pressure is suitable.
3.clear up all the part ,nozzle,manifold, connect part..
The most important issue is to ensure the seal ring, whether it is ok.

The third reason is that the raw material viscosity is too high, in this condition we should increase the material temperature to reduce the flowing material viscosity. and of course the raw material match the preform is the most important idea. The last reason is that the flowing material heating is too lower , can not flowing smoothly. When this phenomena happens we should first increase the runner temperature and the nozzle tip temperature.
