Automatic valve gate preform injection mold
I.Whole mold:
The structure of the mould is very precise, all the moulds are nitrogen zed which could help keep the appearance color of the mould.(Deep brown);
All moulds are kept in the vacuum condition under 500 centigrade degree for 36 hours. After cooling down, the moulds are taken out of the oven. This processing technology contributes to non- distortion, non-transfigure of the moulds.
The rack of the mould is processed once for all which guarantee the concentricity and the precision of the moulds;
The mould closing of slides adopt HUSKY mechanical type, the structure is reliable, each step of the closing and opening of the molds coordinated well, all glide components contact surface uses the advanced nitrogenation, degree of hardness of the mould surface may reach HRC65-70, the friction factor is small, and the surface could endure friction well;
The mould opening of the slides (the Haff block) use the HUSKY mechanical type to open the mold;
Formed parts(cores, cavities and mould lips):
We use Husky bipyramid localization principle, the manufacturing process is highly precise which ensure low decentration of products;
The mold lips are processed by authentic Swiss equipment with accurate measurements;
All formed parts are nitrogenized which could make the surface hard and smooth. This could lengthen the life of the parts;
II.Hot runner parts:
We use Italian Brand Hafshof hot runner tube in our hot runners. The lines are immersed in the board so as to avoid damage;
We use Husky authentic heating coil as our hot mouth, which guarantee the quality.( Our customers reflected that they used this for three years and the parts are still good);
The structure of the hot mouth is Nestal structure. It adopted inclined hopper. The hopper path is smooth and could cooperate with the spinals accurately. The spinal precision is high (within 0.004mm). Hardness of the surface is HRC68-72;
Front end of the hot mouth (injection mouth) uses the Titanium alloy material, which transfers heat quickly, endures friction, long-term guarantee quality;
The spinals are authentic imported spinals.HRC60-65 surface is processed particularly with high precision and friction endurance;
The piston and the cylinder use the imported friction-resisting link, the service life is long, the piston material quality use imported S136, and are precisely processed after heat treatment, seal parts also use imported ones;
Main runners are manufactured by accurate equipment, the runners are highly precise, the surface is smooth, the resistance is small, which could prevent carbonization. Performs are transparent and clear;
Hot runners are made of imported high quality S136. After the rough processing, then keep the hot runners under the vacuum state 550°C-250°C for 48 hours, this could eliminate the mold the possible distortion which is caused by heating up. After the rehearsal, the overall performance of the mould is good;
The cooling performance of the hot mould is good, in the normal injection process, outside temperature of the mold is very low (approximately 40-55°C), which eliminates the disadvantage factor like thermal deformation and swelling of the mould templates of the injection molding machine caused by hot runners heating.
