ABS plastic injection mold

FAQ

Q: What's your yearly turnover in recent 5 years? And what's the proportion of different size molds？

A: In recent 5 years, The average annual sales are about eight million dollars.

Q: What is your smallest tolerance which you can do ?
A: Part tolerance depends on part size, normally we can archieve 16472 group TG4, for steel, smallest tolerance is 0.002mm.

Q: What's the proportion of different size molds？
A: Under 400mm is 30%, 400-900mm is about 50%, above 900mm is about 20%

Q: How many shifts of your workshop?
A: 2 shifts, 8 hours of 1 shift.

Q: Can you make 2k mold?
A: Yes, we can make.

Q: How to design successful plastic mould?
A: Closely related to mold design and manufacturing and plastics processing. The success or failure of the plastic processing
depends largely on the mold design effects and the quality of mold manufacturing, plastic mould design and plastics design.
Therefore, the plastic mould in the design to take full account of structural elements, mainly:
1st, Confirm with customer via DFM, to find what's the requirements on parts, and what's the potential problem on manufacture and moulding;
2nd, Analyze the gate location by mold flow simulation, and find the problems on moulding, such as weld line, shrink mark, air traps and deflection etc;
3rd, Hold a meeting with designer, manufacture Dept and moulding guy to review the design drawing.to check all items show in special list.
4th, All detail design drawing will be checked by supervisor.

Q: We have ever been encountered the appearance issues while mass production,It is the trouble thing for us, which cost a lot of time and money to repair.How to verify injection mould before shipment, how to find the ROBUST process parameter?
A: We'll run 2-3 hours for every mould before shipment,to verify if there is any potential issues,and will improve them if exist.
Regarding the process parameter,we'll confirm the spotting quality of tool at first, and then we always use below guidance to find the applicable injection speed, pressure and the time of gate seal, to ensure we can find a moderate parameter.
