》PET blood test tube gate is white
1. Deformed PET test tube, poor passage degree.
Zhenxiong designs special nozzle for PET material particularity, the concentricity of the test tube is 0.02, and the tolerance of the mouth is 0.01~0.02.
2. The gate has edge or burr to affect the appearance.
The different center of gate and valve will lead to the cutting edge of the gate. The zhenxiong valve needle is located in the nozzle, and the gate is positioned to ensure that the gate and valve needle are concentric.
3. The gate design of nozzle is unreasonable, and the gate is white
The PET gate is fully designed for water line, which can solve the problem of whitening.
PET material is crystallized plastic, which has high requirements for the design of water line around the gate. High gate temperature and unreasonable cooling design will lead to whitening. Zhenxiong professional technical team has overcome this problem, and can provide a complete set of front molds to the customer, which is easier to install.
》48 cavities side-gate injection technical solutions .
A. A device is installed on the top of the system to directly adjust the length of the nozzle core, with A debugging accuracy up to 0.03mm, thus eliminating the steps of removing the nozzle core.
B. The special nozzle core structure with patent intellectual property rights can be used to precisely adjust the position of the nozzle core, so that the nozzle core length is consistent, the injection molding is balanced, and the side-gate injection system with telescopic function is suitable for high precision plastic products
The heatcoil of the sprue makes the heating more even and stable and prolongs the service life.
(syringes) small spacing products, side-gate injection, full hot runner solutions
The square nozzles with small spacing developed by zhenxiong, with the spacing of gate points of 8mm, are professionally applied to the colorific cup products, which can molding PP,PS,ABS, etc., with stable production and good balance effect.
