Semiconductor Equipment Model Manufacturer

Semiconductor Equipment Model Precision Manufacturing Case Study

Project Objectives

Customise a semiconductor process equipment model for a client, reproducing over 90% of the structural details of the actual equipment, with a focus on the robotic arm movement mechanism and modular cabin design.

1. Main Structure Manufacturing Process

Frame Construction

The main frame substrate is CNC-cut from high-density aerospace laminate panels, with laser-guided alignment and assembly for the load-bearing structure.

The cabin outer shell is vacuum-moulded from ABS engineering plastic, with critical curved surfaces reverse-engineered via 3D scanning to ensure arc joint gaps ≤0.1mm.

Precision Reconstruction of the Robotic Arm

Main joints: 316 stainless steel precision cast and CNC milled, with mirror-polished surfaces.  

Movement mechanisms: 3D-printed nylon gear sets paired with miniature ball bearings to achieve a 270° real-world movement range.  

End effectors: Aluminium alloy etching process to replicate real claw textures.  

2. Industrial-Grade Detail Processing

Multi-colour coating system

Primer treatment: Sandblasted entire piece, then coated with epoxy primer to enhance adhesion

Main colour process:

Body: 5 layers of matte white automotive paint (including UV curing layer) to simulate industrial paint texture

Feature red line: Ferrari metallic red paint applied using masking spray technique, with sharp edges and no bleeding

Metal components: Electroplated matte silver layered coating, retaining the casting texture

Control panel simulation

Buttons: Silicone moulded, with LED micro-lights embedded at the bottom

Screen: High-transparency PMMA laser-engraved and screen-printed display interface

Emergency stop button: Independent metal knob with spring-loaded feedback

III. Dynamic system integration

Transparent cabin construction

Observation window uses anti-glare acrylic panels with internal etched equipment identification markings

Layered chamber structure: laser-cut 2mm transparent resin panels, argon arc welding method for assembly

Motion mechanism calibration

Robotic arm pre-installed with miniature servo motors, using magnetic coupling brushless transmission to reduce noise
