PC Plastics Application-Home Appliance Molds

PC plastic material is widely used in lens mold, displayer molds or panel molds of home appliance and drawers  molds of freezer. When making the mold design for PC part, we should know well about its injection molding features otherwise it is hard to deliver the qualified samples for customers' approval.

1, Preparation before injection:

Water absorption of PC plastic materials is large, the PC ram material must be dry before injection, pure PC shoule be drying in 120 ℃, modified PC Chips with a temperature of 110 ℃ dried for more than 4 hours. Drying time can not exceed 10 hours. Generally available air extrusion method can determine whether the material is sufficient drying. 

2, Injection molding machine selection:

PC plastic products due to cost and other aspects, the use of modified materials, particularly electrical products, should also increase the fire resistance, in the flame-retardant PC alloy products and other plastic molding,plastics mixing system of injection molding machines required good resistance to corrosion, conventional plasticizing screw is difficult to achieve, So, PC screw was suggested to make PC parts.Normally, we will use DAKUMAR Injection  Machine PC screw injection machine.

3, Mold design and Injection gate location selection:

Common mold temperature of 80-100 ℃, with fiberglass is 100-130 ℃, small articles can use point gate, and gate depth should be 70% of the thickest parts. For freezer drawer molds, we will used hot runner valve gate, the hot runner system can be YUDO, HASKY,MOLDMASTER ...and of the other  cold runner gate is edge gate or rectangular gate. Gate is bigger, the injection is better in order to reduce PC plastic flowing resistance through the gate. Air vent slots depth should be less than 0.03-0.06mm, the flow path as short and round, draft angle is is generally about 30'-1.

4, Melt temperature:

 General PC plastics processing temperature of 270-320 ℃, some modified or low molecular weight PC plastic materials for the 230-270 ℃.

5. Injection speed:

Common with relatively fast speed injection molding, like electrical switches , Slow - rapid forming.

Long residence time at high temperature in the injection machine barrel, the material will be degraded, put CO2, the material turns yellow. 

Do not use LDPE, POM, ABS or PA clean up barrel, please use PS !

Hope the PC Plastics Application-Home Appliance Molds is useful for you, Sino Mould is good at design and manufacturing home appliance molds.

Home Appliance Mould

Sino Mould Co.,LTD, located in China mold town, with 24 years’ experience for designing and making plastic injection molds for electrical appliance. Sino Mould can use high end home appliance molding technology, and supply home appliance mold to the world, also help to make home appliance trial production to make the molds structure more stable.

Now home appliance molds are getting more and more popular in mold making industry. And the customers need home appliance molds with high fitting ability and high quality surface treatments. Generally speaking, home appliance mold steel is like Nak80, DIN1.2738, 718H, DIN1.2311 … These kinds of mold steel not only can meet the hardness for home appliance molds, but also offer polishing ability. 
The steel hardness is NAK80>DIN1.2738>718H>DIN1.2311, 

and the shininess is NAK80>DIN1.2738>718H>DIN1.2311.  
Home appliance mold’s polishing is good or not, will caused the surface quality of the home appliances. Another important factor is surface treatment, like texture, high gloss are the most common ways to beautify the home appliance surface.
So, we will suggest high gloss parts to use NAK80 or DIN1.2738 and use 718H for texture surface and DIN1.2311 for some inner parts.

Above 90% home appliance mold comes from China, some famous home appliance brands, like Midea, Haier, Galanz, LG, SHARP,PANASONIC, make their home appliance molds in China, we have made molds for some foreign local brands Kiriazi ,Unionarire/Electronlux in Eyppt, Zamil in Saudi Arabia...

If you are finding good quality home appliance molds make in China, dont hesitate to contact us, we will invite you to have a real visit to our mold factory to see the workshop, facilities, managements.
