Basic process and precautions of precision plastic mold inserts processing

Dongguan Yize mould professional custom precision plastic mold and precision plastic mold inserts and other precision spare parts, according to Yize site for many years of processing experience of the processing personnel, we summarize our precision plastic mold inserts processing basic process and precautions:

1. Deep hole drill
Note: pay attention to the shape quantity, take the number from the middle or one side more than 0.25
2. CNC roughening
Note: when CNC is rough, try to drill the center point of the hole, and pay attention to the datum
3. Milling machine
Note: pay attention to the depth of the screw hole, screw teeth must be vertical (machine attack), pay attention to the thread hole and avoid empty hole, large hole thread hole to the side as far as possible
4. Heat treatment
Note: remember to do cryogenic treatment
5. Big water mill
Note: the big water mill must pay attention to the hole position, the shape must leave 0.05-0.07mm margin, and the right angle should be as good as possible

6. Thick wire cutting
Note: pay attention to the direction and reference level
7. Grinding and fine grasping
Note: pay attention to whether the large surface is deformed, the right angle must be repaired and checked, and 0.003-0.05mm allowance shall be left for the shape. Chamfering, chamfering attention may have edge can not be chamfered
8. CNC finishing
Note: CNC four sides in the finishing, pay attention to the thickness allowance, the depth needs to be deepened
9. CNC center
Note: check the plane and right angle, grasp the center of CNC in the width direction of the factory, and leave margin in the middle
10. Wire cutting and fine cutting
Note: four sides of the line cut, pay attention to the actual match and position measurement, not eccentric
11. Discharge
Note: the CNC can not be in place and the drawing mouth need to discharge, discharge to line cutting surface benchmark processing
12. Fine grinding of grinder in place
Note: take the line cut square hole as the standard, grind the profile in place, measure the depth of CNC surface when grinding the thickness, and determine the allowance of each surface

The above is the basic process of precision plastic mold inserts processing, whether it is precision core and cavity customization or other precision mold parts customization, Yize mould always adheres to carry forward the "spirit of ingenuity", and each process is strictly standardized to protect the quality of customers' products.
