Post-Processing & Assembly
From raw molded part to market-ready product
From raw molded part to market-ready product
What is Post-Processing and why it’s critical
Post-processing means every operation that improves appearance, function, or durability after the part leaves the injection mold.
For most plastic products, post-processing is what turns a “component” into a “finished good” that can be sold at premium price.
We perform 13 of the most demanded post-processing operations:
| Process | Why buyers need it |
|---|---|
| Electroplating (Chrome) | Luxury automotive, cosmetics, sanitary parts |
| Vacuum Metallizing (PVD) | Mirror-like chrome without heavy metals (eco-friendly) |
| Painting & Soft-Touch | Piano black, matte, rubberized feel, anti-scratch |
| Pad Printing | Logos & icons on curved or textured surfaces |
| Hot Stamping | Metallic gold / silver foil, luxury look |
| Silk-Screen Printing | Large flat graphics, durable |
| Laser Etching / Marking | Permanent serial numbers, no ink peeling |
| UV Hard Coating | Scratch-resistant lenses & transparent parts |
| EMI / RFI Shielding | Conductive coating for electronic housings |
| Texture & Grain Etching | Leather, wood, geometric patterns on mold surface |
All processes are RoHS / REACH compliant and include full thickness & adhesion testing.
Assembly – The final step before shipping
After the part looks perfect, we assemble it into the finished product you actually sell.
| Assembly Process | Why it matters to you |
|---|---|
| Ultrasonic Welding | Strong, clean, hermetic seal |
| Heat Staking & Inserting | Replaces metal nuts, zero loose parts |
| Mechanical Assembly | Screws, clips, springs, metal brackets |
| Snap-Fit & Press Assembly | Fast, no extra hardware |
| Adhesive Bonding | Structural or flexible bonding |
| Leak & Functional Testing | Medical & automotive parts must work first time |
| Cleanroom Assembly (ISO 8) | Medical devices, baby products, some electronics |
| Final Packaging & Labeling | Retail-ready or ocean-freight safe |
