Capability Overview

Injection Molding

Injection molding is the most common plastics process for US buyers sourcing OEM parts from Asia. Factories run multi-cavity molds on hydraulic or electric presses with cycle times measured in seconds.

Our network includes injection molders in Guangdong, Bangkok, and Penang with ISO 9001, FDA food-contact pathways, and export experience to US retail and wholesale channels.

Sourcing Specs

MOQ & Lead Times

Typical ranges from network profiles — your program may differ based on tooling, volume, and factory load.

Minimum order quantity (MOQ)

Typical volume MOQ: 3,000–10,000 pcs per SKU (existing tooling)
Pilot / sample run: 500–1,500 pcs sample run before volume PO
Notes: New tooling MOQ often 10,000+ pcs amortized over mold cost. Thailand partners may accept lower pilot MOQs for irrigation programs.

Lead times

Samples: 7–14 days (existing mold) · 4–6 weeks (T1 samples on new mold)
Tooling: 4–8 weeks new steel mold · 2–3 weeks aluminum prototype mold
Production: 4–6 weeks after sample approval
Export staging: 3–5 days FOB port consolidation

Materials

Material Options

Common resin grades and applications — specify exact grade and certification requirements in your RFQ.

Grade / material	Typical use case
PP (homopolymer / copolymer)	Irrigation fittings, containers, living hinges
ABS / PC-ABS	Electronics housings, impact-resistant consumer parts
Nylon (PA6 / PA66)	Structural components, gears, under-hood automotive
PET / PETG	Clear packaging, food-contact with migration testing
TPU / TPE	Soft-touch grips, seals, overmold applications
UV-stabilized grades	Outdoor irrigation and ag equipment — specify ASTM G154 exposure

Quality

Quality Control

Standard QC pathways at network profiles for this capability.

First-article inspection (FAI) with dimensional report before mass production
Inline QC: cavity pressure monitoring, short-shot detection, visual standards
AQL sampling per ANSI/ASQ Z1.4 — typically AQL 1.0 major / 2.5 minor for retail programs
Material lot traceability and resin certificate of analysis (CoA) on file
Third-party pre-shipment inspection (SGS, BV) available before release

Export

Export Notes

Documentation and logistics considerations for US-bound shipments.

FOB Shanghai, Yantian, Laem Chabang, or Port Klang depending on factory location
HS code classification support for molded plastics (Chapters 39, 84, 85)
RoHS and REACH material declarations for electronics housings
FDA food-contact migration test reports for beverage and food-adjacent packaging
Mold ownership clause must be documented — VFG recommends buyer-owned tooling for strategic SKUs

US Buyers

What to Specify in Your RFQ

Include these details when requesting quotes for this capability.
