We sincerely welcome customers from both at home and abroad to come to negotiate business with us. for Television Front Frame Housing Plastic Mould,Computer Back Cover Housing Plastic Mould,Display Back Cover Housing Plastic Mould. Sincerely hope we are rising up along with our shoppers everywhere in the world.
The housing of the television has a front frame and a back cover, The quality of the outer surface is required no flash, marks of ejection and any scratching. At the same time, this is main structure of television and display devices, it requests strong not weak on the Television Housing Injection Mould, welding line posotion must be considered during mould design.
Considering Television and Display Housing and Back Cover is not transparent, Usually, the greater the crystallinity, the greater the density of plastics and the greater the rigidity, and corrosion resistance must be considered, ABS plastic resin is the first option for molding material. Ceeo company has a group of engineering members who are professional to analyse product structure and mould design, they are skilled with good knowledge of molding. It's very important to design the moud at the beginning. For example, parting surface and parting line definition. We must consider them as follows:
Easy to demould, keep the part in the core side of mould for better ejection and also it's better for parting line in side surface and core pulling
Ensure that the exterior surface of Television and Display Housing Part is not damaged
- Ensure dimensional accuracy of Television and Display Housing and Back Cover part
- Better with venting on mould
It must consider that it's easy for mould machining
Gate position design for Television Front Frame and Back Cover ( Display Housing ) Plastic Mould
In the design of this injection mould, the position and size of the gate are strict, so it may be necessary to modify the size of the gate after the initial mold test. we normally consider the following:
- The gate should be set at the maximum wall thickness of part
- It must reduce welding lines
- It's be good of mould venting
Consider the effect of molecular orientation
Due to the relatively large volume of the plastic parts, the relatively high temperature of the part of the die kernel, and the lower temperature caused by the external contact with air, the temperature is prone to produce uneven temperature distribution, and the characteristics of the mould materials such as thermal expansion, cold expansion and contraction. So that the mold will produce varying degrees of deformation, so cooling line design is very critical.
- Try to keep the plastic parts shrink evenly and maintain the heat balance of the mould
- The more plastic the cooling water hole is, the larger the aperture is, and the more uniform the cooling effect is to the plastic parts
As far as possible the distance from the cooling water hole to the surface of the cavity is equal
- Enhanced cooling at gate
- Reducing the temperature difference between water line in and out
- Properly choose water line plug position
To avoid inteference with the other structure of mould
