Process

01

High Pressure Aluminium alloy die cast

Equipment: 350T cold chamber aluminium die casting machine
Material: ADC12 (US-383/Russia-AJ16/German-AlSi8Cu3/UK-LM2/Italy-4520/Eu-ENAC-46400)

Process Features:

a. Furnace temp: 650°±20°, Material handle: 20±2MM

b. Secondary materials cannot be used

c. Test material composition before production

d. First piece confirmation required

Precautions: a. Confirm surface filling quality. No cold insulation, bulging, or lack of material. b. Avoid sticking, drawing molds, or poor ejector pin convexity. c. Ejector pins concave 0-0.2mm for non-machine-added surfaces, and convex 0-0.2mm for machine-added surfaces.
02

Degating (Saw gate & knock out slag bag)

Equipment: Sawing machine
Tools: Wooden stick
Precautions: Do not allow breaking at the mouth of the chipping; residual height must be less than 2mm.
03

Input Process Quality Control Inspection

Test tools: Caliper / Projection / 3.0 coordinate measure machine / Visual inspection

Check dimensions according to drawings.

Precautions: Use measuring tools correctly and verify all dimensions.
04

Shaping

Equipment: Shaping tooling

Partially shape the shrinkage area of the flange face at the main slag outlet.

Precautions: Do not allow deformation or cracking.
05

CNC (First Clip)

Equipment & Tools: CNC machine, φ2.5/φ3.3/φ5 drills, M3/M4/M6 taps

Drilling and Tapping:

1. 8x M6 deep 14mm threads

2. 1x M3 deep 6.5mm thread

3. 1x M4 deep 8mm thread

4. Milling the sprue bit

Precautions: a. Do not overcut or miss processing. b. Prevent surface bruises and burrs. c. Ensure surface finish of Ra0.8, and maintain size/shape tolerances.
06

Input Process Quality Control Inspection

Flatness verification for the shaping process.

Precautions: Inspect the flatness to ensure shaping is in place.
07

Grinding (Smooth Mold Line)

Equipment: Eccentric sanders, concentric sanders
Precautions: Surface transition areas must be jointed smoothly. No collapsing, touching, or missing spots allowed.
08

CNC Second & Third Clip (4-Axis)

Equipment: CNC, 4-axis fixture, 4-axis rotary table, φ8 milling cutter, φ2.5/φ10.5 drills, M3/M12 taps, T milling cutter φ18*3.5*50L

Second Clip: 16x M3 deep 9, 3x M3 deep 9, 5x M3 deep 7, 7x M3 deep 12.5 (all chamfered C0.5); mill slag residue.

Third Clip: 2x M3 deep 6.5, 1x M12 deep (chamfer C0.5), 1x M25 deep 10 (chamfer C0.5, root avoidance ~2.5mm); mill sprue residue.

Precautions: 1. Do not overcut or miss processing. 2. Avoid surface bruises and burrs. 3. Maintain Ra0.8 finish and all tolerances.
09

Input Process Quality Control Inspection

Tools: M3/M4/M6/M12/M25 Thread Gauge (6H)

Appearance visual inspection and thread verification.

Precautions: Confirm thread conformity with specified gauges.
10

Grinding and Deburring

Equipment: Flat/round frustration, air grinder, pneumatic file

Chamfer and deburr sharp corners; sand and smooth all edges.

Precautions: No sharp corners or burrs. Connect smooth mold lines to level R Angle.
11

Input Process Quality Control Inspection

Visual inspection of the overall appearance after grinding.

Precautions: Ensure smooth surfaces and check for defects.
12

Full Inspection Before Powder Coating

Check whether the contents of each process are in place and whether there is any omission of processing before powder coating.

Precautions: a. Inspect appearance according to sample (no dirt, scratches, defects). b. Tooth pattern must check out with the stop gauge.
13

Outsourcing: Powder Spraying

Area-specific powder spraying process.

Precautions: Gloss level 30, film thickness 80-200μm.
14

Incoming Quality Control Inspection

Visual inspection of appearance and adhesion tests.

Precautions: a. Confirm surface quality post-coating. b. Sample check holes with needle gauge / through-hole inspection with stop gauge.
15

Full Inspection (Appearance + Packaging)

Final detailing inspection before product packaging.

Precautions: a. Inspect against sample; surface must be free of dirt, scratches, dents; glue dispensing must be even. b. Tooth pattern must comply with go/no-go gauge. c. Place in knife card with flat cardboard cover.
16

Final Quality Control Inspection

Tools: Caliper, projection, needle gauge, tooth gauge, packaging inspection
Precautions: Verify whether the measuring tools are within their calibration period.
17

Shipping

Product dispatch preparation.

Precautions: a. Match quantity with order. b. Apply label and stamp on the outer box. c. Provide shipping report.
