b. Secondary materials cannot be used
c. Test the material composition to confirm that it is OK before production
d. First piece confirmation is required
Precautions
a. Confirm the filling quality of the surface. No cold insulation, no bulging, or lack of material for the pillars.
b. Pay attention to the surface to avoid sticking molds, drawing molds, or poor ejector pin convexity.
c. The ejector pins are concave by 0-0.2mm for non-machine-added surfaces and 0-0.2mm for machine-added surfaces. The thimble needs to be convex 0-0.2mm.

Precautions
a. Do not overcut, missed processing.
b. Surface attention must not be bruised, burrs.
c. Ensure that the surface finish Ra0.8, size, shape and location tolerances.
6

InPut Process Quality Control inspection

Quality verification step following the first CNC clip.
Precautions
Inspect the flatness for shaping in place.
7

Grinding (Grinding of smooth mold line)

Equipment: Eccentric sanders, concentric sanders
Precautions
Surface transition areas need to be jointed smoothly, do not allow collapsing, touching and missing.
8

CNC Second clip and Third clip (4-axis)

Second clip - Drilled and tapped; milled slag pack residue:
a. 16x M3 deep 9 orifices chamfered C0.5
b. 3x M3 deep 9 holes chamfered C0.5
c. 5x M3 deep 7 holes chamfer C0.5
d. 7x M3 deep 12.5 orifice chamfer C0.5
e. Milling slag packet residue
Third clip - Drilling and tapping; milling into sprue residue:
a. 2x M3 deep 6.5 holes chamfered C0.5
b. 1x M12 deep penetration orifice chamfer C0.5
c. 1x M25 deep 10 orifice chamfer C0.5 (root avoidance of about 2.5mm)
d. Milling into the sprue residue
Equipment and tools:
CNC machine, 4-axis fixture, 4-axis rotary table; φ8 milling cutter, φ2.5/φ10.5 drills, M3/M12 taps, milling cutter (milling M25), T milling cutter φ18*3.5*50L
Precautions
