Chinese Battery Box Mold Maker

We are engaged in manufacturing, exporting and supplying a wide range of battery box molds.The offered range is available in various specifications as per customers’ requirements. Due to customers' trust, every year we export about 80sets battery box molds to all over the world and has enjoyed wide acclaim.

Commonly, battery box includes two parts: one is battery box base, another one is battery box cover. Below are specifications of battery box molds made by Sino Mould:

Product material: PP

Mold steel: DIN1.2738, 718H, P20

Mold life: 500K

Runner type: hot runner, one tip for battery box cover mold; but for battery box base mold, we suggest one tip for one lattice

Eject way: ejector pin for battery box cover; stripper plate for battery box base

The most important key point for battery box mold is to master how to control each lattice size, neither too loose nor too tight. If it is too loose, the battery box will get swell when charging; If it is too tight, the battery box will fail to charge. So our company had spent a lot of time to figure out the best solution to control the size. Before mold design, our engineer will do moldflow to analysis the deformation. According to the moldflow report, our designers will choose suitable position for injection point to keep injection balance. Also we will make the water channel more intensive to reach good cooling effect.

Plastic Chair Molding Service

Sino is specialized in design and manufacture various types of chair mold, like PC chair mold, PP chair mold, gas assisted chair mold, child chair mold and so on. Almost most of the mold company can make chair mold, but seldom of them know how to make a high quality chair mold with good price. That’s why more and more company closed down, while Sino become stronger and stronger.

 

Some key points to check if the chair molds high quality and not:

1. Chair mold running cycle time

If the chair weight from 1700g to 2400g, the cycle time should be 35s to 50s. If the machine plastic melt and inject are with accumulators. Please check how they make the cooling channel? The cooling channel is extra in and out?

 

2. Chair mold guaranteed life

Most of manufacturers will say that their molds will have one millions guaranteed life. But God now how can they guarantee. Can the mold run 1 million shorts without any flashes? Because if you accept to cut the flash by your workers heavy labor, I think you can use this mold for 10 millions shorts. So you need to check the steel hardness, and in the mold if there is any parting area were welded. Normally the steel hardness should be HRC33.

 

3. Double check the parting line finishing, if there has any sharp edges?

First you have to check the chair mold parting line is correct or not. You have to know how the CNC milling the cavity and core. Are they one stage finishing or several stage finishing?

 

4. Double check the wall thickness, is it even or not?

The uneven thick will cause the injection not balance and also will cause the cooling time not even, which will affect the injection speed slow down and also will cause the shrinkage marks. If the CNC milling is too rough, you can never get a chair with thickness even.

5. Check the stackable

When the chair plastic design is doing, we have to check its stackability. And you also need to consider the deform possibility of the chair molding.
 

All in all, one high quality chair mold must be with short cycle time, long mold life, perfect parting line finishing, good stackability, well air vent design, less weight but strong enough. If you have idea want to develop chair mold, please kindly contact me, I am glad to offer you best chair molding solution.
