No Outsourcing. No Handoffs
Everything Finished
Under One Roof
Finishing is commonly outsourced by injection molders, which adds lead time, logistics risk, and IP exposure at every handoff. At AMP, decoration, marking, and surface treatment are part of the same production flow as molding. Your parts are finished by our own team in our own facility, and you deal with one supplier from raw material through to packaged product.
We run the following finishing processes in-house across our Taiwan and Thailand operations:
PRODUCT FINISHING
HEAT SET INSERT / ASSEMBLY/ PAINTING
GRAPHICS & BRANDING
PRINTING (SCREEN & TRANSFER) IN-MOLD LABELING (IML)
Scope
Compatible Materials & Applications
Our finishing processes cover the full range of materials we mold, including ABS, PC, PP, PE, PMMA, PS, PCTG, and PC+ABS. Applications span consumer electronics, home appliances, automotive parts, and food containers depending on the process.
Not every process suits every part. If your design includes finishing requirements, include them in your RFQ and we will confirm which processes apply and whether any geometry or material constraints affect the approach.
Engineering plastics: ABS, PC, PC+ABS
Commodity plastics: PP, PE, PS
Clear / Specialty plastics: PMMA, PCTG
Quality Control
Appearance Inspection Before Shipment
Finished parts are checked against approved reference samples before leaving the production line. Our QA team inspects for surface defects covering the full range of injection molding and finishing outcomes, including bubbles, sink marks, scratches, color variation, flash, contamination, and incomplete fill. Inspection records are included with your production documentation.
ISO 9001 quality framework
ISO 14001 environmental management

Product Finishing FAQ

Screen printing, transfer printing, in-mold labeling, laser engraving, spray painting, and sandblasting are all performed in-house at our Taiwan and Thailand facilities. None of these are outsourced to third-party suppliers.
Yes. Our finishing processes cover products across consumer electronics, home appliances, automotive components, and food containers. The right process depends on your material, part geometry, and decoration requirements. Include your finishing spec in your RFQ and we will confirm what applies.
We laser engrave ABS, PC, ABS+PC, PA, and PBT. The process produces permanent markings including logos, QR codes, barcodes, serial numbers, batch codes, and regulatory symbols such as CE, RoHS, and voltage ratings. Because each part can be programmed individually, variable data such as serial numbers can differ unit to unit at no added setup cost.
Both. Spray coating improves surface hardness, abrasion resistance, UV resistance, and weather resistance in addition to providing color finish. Functional coating requirements should be specified in your RFQ so we can confirm the right coating system for your application.
In-mold labeling integrates a pre-printed label directly into the part during the injection molding cycle, so no secondary decoration step is required. The label is bonded to the part rather than applied afterward, which produces a more durable finish. It is most commonly used on food containers and consumer packaging where high-resolution graphics and color consistency matter.
Transfer printing and in-mold labeling are both used on food containers we produce. If your application has specific compliance requirements, include them in your RFQ so we can confirm the appropriate process and materials.
