if there is a problem of mould, review the mould�檚 coordination and dimension, re-adjust mould if need; Try to adjust on machines; if failed, the product structure or material should be revised.4.

Solution: Revise the unreasonable structure through software for 3D drawing, or redesign the whole drawing, what got the final approval could be passed to workshop.

2.Burr come out in plastic injection products producing

Solution: Check that if it was led by exceeded injection pressure, if yes, adjust the injection machine for further process; if there is a problem of mould, review the mould’s coordination and dimension, re-adjust mould if need; for partial burr, could be replaced by insert or welded.

3. Shrinkage in Producing

Solution: Check the problems on design, such as if it has too thick place or big thickness distance, if gate location and air-exhaust equipments are reasonable. Try to adjust on machines; if failed, the product structure or material should be revised.

4. Scratch and Blushing in Producing

Solution:   1) Do polishing, especially in rib, to reduce the resistance when ejecting. 
                2) Net-veined for ejector face, to increase the area of pressure. 
                3) Shorten ejector by 0.1-0.3 mm to increase the thickness 
                4) Make the corner on insert into fillet, to reduce the resistance when ejecting.
