Beyond toolmaking, Hongqiang Mould runs custom plastic injection molding for production parts – from first samples to repeat orders. As an OEM/ODM injection molding manufacturer serving export buyers, we work directly from your 2D/3D drawings: send the part, material target and annual volume, and our engineers reply with DFM feedback and a quotation within 24 hours.
Production floor
Molding, finishing and packing run in line on the production floor.
Injection Molding Capability
Confirmed, verifiable numbers – no estimates. Molding here runs on 11 presses from 80 to 450 tons, with inspection backed by our metrology room (see the equipment on the engineering page).
| Injection machines | 11 presses, 80–450 T clamping force |
| CNC machines | 5 CNC machining centers for mould making |
| Materials | PP, PE, ABS, PS, PC, PA, POM, PBT, PET, TPE, TPU – transparent parts available |
| Insert & overmolding | Handled in-house: metal inserts, threaded inserts, multi-material |
| Tooling lead time | About 45 days typical for small moulds (quoted per project) |
| Production scope | Prototype and pilot runs through repeat mass production |
| Quality inspection | Bridge CMM, video measuring machine (JATAI), material tensile tester, calipers and micrometers |
Materials We Mold
Commodity plastics: PP, PE, ABS, PS
Engineering plastics: PC, PA, POM, PBT, PET
Elastomers: TPE, TPU
Transparent parts: available
Material availability is confirmed per project in DFM – tell us your resin target and we validate it against the tool and press before steel is cut.
Production Molding
Parts are molded on 11 presses from 80 to 450 tons, matched to the tool and material – from low-volume pilot runs to mass-production repeat orders. Processing parameters are recorded per batch, so results stay traceable and repeatable across orders.
Insert Molding & Overmolding
Metal inserts, threaded bosses and multi-material overmolding are handled in-house where the tool design calls for it, keeping secondary sourcing off your critical path.
Secondary Operations
Degating, finishing, printing and simple assembly keep parts shipment-ready from one supplier – no third-party handling between molding and packing.
From RFQ to Serial Production
- RFQ – send drawings (2D/3D), material target and annual volume.
- DFM & quotation – engineering feedback plus a quotation within 24 hours.
- Tool design approval – then steel ordering and machining.
- Trials & sampling – sign-off on samples before serial production.
- Serial molding – production with batch records.
- Packing & shipment – export-ready packing.
Quality Control at the Press
Every program follows the same inspection sequence, documented per the agreement in your RFQ:
- 01 Incoming tool inspection
- 02 First-article inspection
- 03 Dimensional sampling
- 04 Process monitoring – parameters recorded per batch
- 05 Final inspection before packing
- 06 Inspection report supplied per RFQ agreement
CMM inspection
The bridge CMM backs every dimensional report with measured data.
2D video measurement
2D video measurement checks profile and thin-wall dimensions on samples.
Material testing
The tensile tester confirms material behavior against the resin data sheet.
Why Hongqiang Mould
- Tooling + production, one supplier – mould development and serial molding under one roof, so tool fixes and process changes do not cross company boundaries.
- DFM before steel is cut – feedback on draft, wall thickness, gating and ejection before tooling starts.
- Traceable production – batch records for consistent repeat orders.
- Flexible volumes – prototype, pilot runs and repeat mass production.
- Quality documentation – inspection records available per project requirements.

Injection Molding FAQ
What do you need to quote my injection molding project?
Send 2D/3D drawings, your material target and the annual volume. We reply with DFM feedback and a quotation within 24 hours.
Do you provide DFM feedback before tooling?
Yes. Engineering feedback on draft angles, wall thickness, gating and ejection comes before tool design approval, so problems are solved before steel is cut.
Can you produce parts from customer drawings (OEM/ODM)?
Yes – that is our core business. Moulds are built to your drawings and standards, and samples are signed off before serial production.
Do you support insert molding and overmolding?
Yes. Metal inserts, threaded bosses and multi-material overmolding are handled in-house where the tool design calls for it.
Can you handle low-volume and repeat production?
Yes. Programs run from first samples and pilot runs to repeat mass production with batch records.
What quality documents come with the parts?
Incoming, first-article and dimensional inspection records, plus trial documentation, supplied per the agreement in your RFQ.
Can you ship finished parts internationally?
Yes. We serve export buyers and pack for international shipment.
What injection molding machine sizes do you run?
11 injection presses from 80 to 450 tons clamping force. Tools are matched to the press that will run them, so process conditions stay consistent from sampling to serial production.
What plastic materials can you injection mold?
Commodity plastics (PP, PE, ABS, PS), engineering plastics (PC, PA, POM, PBT, PET) and elastomers (TPE, TPU), including transparent parts. Name your material target and we confirm processability in DFM before tooling starts.
How long does tooling take?
Small moulds typically take about 45 days. Larger or multi-cavity tools are scheduled per project and confirmed in the quotation.

Two questions come up in almost every molding RFQ: which press the mould runs in, and what a passed inspection report actually approves. Two field notes from our molding team explain them: how projected area decides press tonnage, and what a passed inspection report approves.
