D-top Mould manufactures custom plastic parts from your product design — including mold making and mass injection molding in one project. If you need finished plastic components rather than a mold, send us your part data and we handle tooling, production and quality so you receive ready-to-use parts. One supplier, one point of responsibility, from first prototype to recurring production batches.
This service is for product companies that want a supply of plastic parts without building and running their own molding line. It covers prototype quantities through mass production — and because the mold shop and molding floor sit under one roof, design feedback, mold corrections and production scheduling stay fast for the whole life of the program.
What We Provide
- Mold design and making for your part — DFM review, mold flow analysis where needed, and tooling built in-house for stable T1 results
- Material selection — PP, ABS, PC, PA, POM, TPE and engineering compounds, matched to your application and compliance needs
- Prototype and low-volume molding for design validation, market testing and early shipments
- Mass production with documented, stable process control
- Assembly, printing and packaging on request — parts arrive ready for your production line
Materials We Mold
| Material | Strengths | Typical Use |
|---|---|---|
| PP | Chemical resistance, cost, living hinges | Containers, housings, caps |
| ABS | Surface finish, impact | Consumer enclosures, trim |
| PC / PC-ABS | Heat, impact, clarity | Device housings, technical parts |
| PA (nylon) | Strength, wear resistance | Brackets, gears, clips |
| POM | Stiffness, low friction | Moving mechanisms, precision parts |
| TPE/TPU | Soft touch, sealing | Grips, gaskets, overmolds |
Material selection weighs mechanical load, temperature, chemical exposure and any regulatory requirement such as food contact or RoHS. For a detailed resin comparison, see our plastic material selection guide.
Typical Applications
- Industrial equipment housings and brackets
- Agricultural machinery components
- Automotive interior and under-hood parts
- Consumer-product enclosures
- Medical and hygiene plastic parts
What You Need to Provide
- 2D or 3D part data — STEP, IGES or PDF with dimensions
- Resin and any compliance requirement (e.g. food-contact, RoHS)
- Expected annual volume or order quantity
- Critical dimensions, tolerances and surface finish
- Target delivery date
Project Flow
- RFQ and DFM review — we check moldability, flag tolerance and material risks, and quote tooling plus part price within 12 hours
- Mold design and making — tooling built and validated in-house
- Mold trial and sample inspection — we send samples with dimensional reports for your approval
- Prototype or low-volume run if needed
- Mass production with in-process quality checks
- Delivery — by batch against your forecast
Quality Control
- First-article inspection (FAI) with full dimensional report before production
- In-process checks on critical dimensions at defined intervals
- Material lot traceability for every batch
- Optional full inspection report per batch
Every tight tolerance is reviewed during DFM — our DFM checklist shows exactly how we separate functional dimensions from commercial ones, so you pay for precision only where it matters.
Frequently Asked Questions
Do I own the mold?
Yes. The mold is built for your part and remains your asset. We keep it in storage for repeat orders and return or transfer it on request.
What volume makes this worthwhile?
From a few hundred prototype parts up to high-volume production. Send your expected quantity and we recommend the most cost-effective tooling — sometimes that means a simpler mold plus higher piece price, sometimes a production tool with amortized cost.
Can you just make the mold and ship it to me?
Yes — if you run molding yourself, see our custom injection mold manufacturing service instead.
How do you protect my part design?
Your drawings and 3D data are used only for your project. We are happy to sign an NDA before you send anything — just ask.
What if the part needs changes after the first trial?
Mold corrections are handled in-house, which is why changes move in days rather than weeks. Steel-safe design principles are applied where future changes are likely.
