HOW IT WORKS
From Inquiry to Delivery
Quote & DFM
Upload a 3D file and get a quotation plus free DFM review. We flag draft angles, wall thickness, gate locations and material fit before any tooling spend.
Mold design & build
In-house tooling engineers cut steel for your part — two-plate, three-plate, hot runner, insert or family molds — with wire EDM (9+4 machines) and precision CNC on site.
Trial shots (T1)
T1 samples are molded on our Sodick presses (18+3 machines), measured against your drawing and returned for approval with the trial report.
Mass production
Production runs are fully parameter-monitored; our IATF16949 / ISO13485 / ISO9001 system keeps every shot within the agreed process window.
Quality inspection
CMM and gauge inspection per DIN-7168-m / ISO 2768-m tolerances, with appearance checks for flash, weld lines, sink marks and surface finish.
Packaging & delivery
Parts are packaged to your spec and shipped globally; low-volume runs leave in 7–12 days, production orders in 25–30 days.

FAQ
Plastic Injection Molding Service — FAQ
Q: What is the minimum order quantity?
A: There is no hard MOQ — unit price drops once volume exceeds roughly 500 pieces, and low-volume runs (7–12 days) cover pilot batches from 100 parts.
Q: Can you sign an NDA before quoting?
A: Yes — an NDA can be signed before the quotation if your design is confidential.
Q: Who owns the mold after the program?
A: You do — the mold is built to your program and stored for free; we also maintain it when we run your production.
Q: How are engineering changes handled?
A: T1 trial samples are your approval gate; changes after T1 are quoted transparently, with mold modification only where the drawing demands it.
Q: What tolerance can you guarantee?
A: Standard molding to ±0.1 mm, precision to ±0.05 mm, verified by first article and CMM reports per DIN-7168-m.
Q: Can you mold with resin I specify?
A: Yes — consigned resin and customer-specified suppliers are supported with documented proof of purchase and inspection.
Q: Do you match custom colors?
A: Pantone / RAL color matching with ΔE ≤ 1.0, including masterbatch and pre-colored resin options.
Q: How fast can production start?
A: Quote and free DFM within 24 h; rapid tooling 7–12 days, production tooling 25–30 days, then mass production with global shipping.

Plastic Injection Molding vs. Plastic Molding: What's the Difference?
'Plastic molding' is an umbrella term covering every process that shapes plastic into a finished form. Injection molding is the specific, highest-precision member of that family — and the one MOLDITQUICK (Dongguan Guohong Precision, 10000 m², 280 staff) runs end-to-end in-house.
Injection molding — precision, at scale
Melted resin is injected under high pressure into a closed steel cavity, then cooled and ejected. It delivers the tightest tolerances (down to ±0.05 mm) and the fastest per-part cost of any plastic molding route once volume is above roughly 500 parts.
- ±0.05 mm precision molding
- Complex 3D geometry in one shot
- Automated cycles for high volume
The wider plastic molding family
Blow molding, rotational molding, compression molding and thermoforming all count as 'plastic molding' too. Each is excellent at one thing — hollow bodies, huge tanks, thermoset strength, sheet parts — but none match injection molding's combination of detail, tolerance and throughput.
- Blow / rotomold / compression / thermoform
- Each optimized for one part family
- Looser tolerances, different economics
Why the distinction matters to buyers
When a sourcing team asks for 'plastic molding parts', the quote depends entirely on which process the supplier assumes. At DFM we pin down the process, the tooling class and the tolerance standard before steel is cut — no surprises at T1 samples.
- DFM locks process + tolerance up front
- In-house tooling, no middleman
- IATF16949 / ISO13485 / ISO9001 quality system
Materials We Injection Mold

Tolerances, Sizes & Lead Times We Hold
Capability windows per FirstMold's injection molding service page (https://firstmold.com/plastic-injection-molding-service/), matched to our in-house Sodick fleet; mold tolerance class per industry-standard DIN-7168-m / ISO 2768-m.
| Capability | Standard | Precision / Notes |
|---|---|---|
| Molding tolerance | ±0.1 mm | ±0.05 mm for precision molding on critical dimensions |
| Mold machining tolerance | ±0.005 mm | Verified by CMM before trial shots |
| Part size range | 5 × 5 × 5 mm to 1500 × 1000 × 500 mm | Large-surface parts on our bigger tonnage presses |
| Machine capacity | 90T–1600T (Sodick 18+3) | 18 standard + 3 two-shot machines in-house |
| Rapid tooling lead time | 7–12 days | Aluminum/soft-steel molds for low volume |
| Production tooling lead time | 25–30 days | Automotive-class programs may run longer |
| Quality standard | DIN-7168-m / ISO 2768-m | CMM + gauge inspection on every program |
Where Plastic Injection Molding Pays
Automotive
Interior trim, brackets, housings and fluid-system parts under IATF16949 control.
Consumer electronics
Enclosures, buttons and internal frames at tight tolerance and high volume.
Medical devices
ISO13485-certified molding for housings and disposable components.
Industrial equipment
Gears, valve bodies, pumps and structural covers that need engineering plastics.
Packaging & consumer goods
Caps, closures, housewares and tools where commodity resins keep cost low.
Low-volume to mass production
One factory spans 100-piece pilot runs and million-piece programs — 7–12 day and 25–30 day tracks.
