Engineer-Led Injection Mold Making & Molding
Built for Reliable Production
KTM designs and builds injection molds in-house, molds plastic parts, and provides CNC machining and rapid prototyping in Dongguan, China. We also manage die-casting tooling and partner production.
Before steel is cut, our engineers review gate, cooling and tolerance risks. Trial samples and dimensional inspection then give your team clear evidence to approve tooling and production.
Our Story
KTM began in 2006 as a small toolroom founded by Mr. Chan. Ramon joined as a mold engineer, later leading mold engineering and taking responsibility for complex tooling projects.
As Ramon's responsibilities grew, he took over day-to-day operations. Following Mr. Chan's passing, Ramon and his brother acquired the company and continued to build its engineering capabilities.
Today, KTM operates a 3,000+ m² facility with approximately 80 people. Its in-house toolroom, CNC equipment and 40+ injection molding machines—including FANUC, Haitian and LOG presses—support projects from mold design through trial and production.
Ramon remains involved in mold design reviews and shop-floor problem solving. That engineering oversight helps the team identify manufacturability risks early, resolve trial findings and deliver tools ready for their intended production environment.
One Engineering Team, From Tooling to Production
KTM brings DFM, moldmaking, in-house injection molding, CNC machining and prototyping into one coordinated workflow. When a project needs high-tonnage molding or casting production, we manage qualified partners and remain accountable for the tooling and agreed deliverables.
Injection Mold Making
Our injection mold manufacturing process matches steel, gating, cooling and moving actions to the part and target volume. DFM and trials verify the tool before handover or production.
Injection Molding & Production
For custom injection molding, we trial tools on in-house 90–400T presses and inspect samples against agreed criteria. KTM coordinates qualified high-tonnage partners when a larger press is needed.
Precision CNC Machining
Our precision CNC machining supports plastic and metal prototypes, mold inserts and finished components. Critical dimensions are measured against the approved drawing before release.
Rapid Prototyping
Use 3D printing to check geometry and fit, then vacuum casting for small-batch appearance and assembly trials. Both reduce design uncertainty before production tooling begins.
Die Casting Tooling
KTM builds aluminum die-casting molds in-house and coordinates zinc die casting with qualified partners. Tool design and inspection follow the agreed part requirements.
Mold Components
Our injection mold components include cavity and core inserts, sliders, lifters and ejector parts. We machine and inspect mating features for fit in the approved tool assembly.
Molds Built to Last
An export mold must perform on the receiving plant's press, with predictable maintenance and service life. We review steel, cooling, wear points and acceptance requirements before manufacture, then document trial results before shipment.
We select steels such as P20, 718/738, H13/8407 or S136 according to the resin, surface finish, expected volume, wear conditions and maintenance plan.
Expected mold life is specified against the chosen steel, part geometry, resin and maintenance plan, from bridge tooling to high-volume production.
Before export, we provide trial samples and the agreed dimensional, inspection and process records so your receiving team can review the mold against its acceptance criteria.
Export molds are cleaned, protected against corrosion and secured in wooden crates. Vacuum packing is available when the shipping conditions call for it.
How We Control Quality
Review before steel. A preliminary DFM review flags draft, wall thickness, undercuts, tolerances and assembly interfaces at quotation. After order confirmation, detailed DFM turns those risks into agreed gate, parting-line, cooling and ejection decisions.
Simulation where it adds value. Mold-flow analysis is used when part geometry or material creates meaningful uncertainty about filling, weld lines, pressure, cooling or warpage. It informs design changes when the risk justifies it; it is not required for every mold.
Checks during toolmaking. Hardness testers verify specified steel condition. Height gauges, micrometers, pin gauges and plug gauges check machined features, while VDI texture reference plates help compare the required surface finish.
Evidence from the trial. CMM and optical measurement check critical dimensions against the approved drawing. Where function depends on fit, we also inspect the part with its mating components against the agreed assembly requirements.
Control of distortion. For parts prone to warpage, dedicated cooling fixtures support geometry as the parts cool. We then remeasure critical features and adjust the process or fixture if the results miss tolerance.
Documented release. Trial samples, dimensional reports and relevant material certificates are supplied at agreed milestones. If a result falls outside the acceptance criteria, our engineers investigate the cause, document corrective action and verify the next trial before release.
Customer drawings and tooling remain project-specific. We support NDAs and control access to files and molds throughout the job.
Our Customers — And Why They Stay
Across automotive, electronics, medical enclosures, industrial equipment and consumer products, customers return for sound DFM, documented trials and responsive engineering. Some relationships have lasted 15+ years; the approvals and factory visits below show that continuity in practice.
A European customer approves T2 samples and confirms that the mold can move to its German plant.
A US customer approves T3 samples and confirms a 10,000-set production order.
A customer's WhatsApp feedback after sample review reflects an open, direct working relationship.
A small thank-you for a customer partnership lasting 15 years.

Our team also visits customers overseas, building working relationships beyond email and trial reports.
Project work behind recognizable product marks. Selected KTM projects have included components bearing Audi, Volkswagen, Honeywell, Siemens, Mercedes-Benz and MAHLE marks. Each program starts with the customer's drawing and assembly requirements, then moves through DFM, controlled trials and dimensional checks. The value is a part that fits its intended assembly and can be produced consistently—not a logo on a first-off sample.

Built for Global Partners
A dedicated English-speaking project engineer keeps design questions, trial findings and next actions clear. Our project and engineering team is available until 8:00 PM China time to overlap with customers in other time zones.
When a feature or trial result needs discussion, you can review it directly with the engineers responsible and agree on the next step by video call.
FANUC CNC and molding equipment, Sodick EDM and in-house inspection support a consistent workflow from tool manufacture to sample approval.
Let's Talk About Your Project
Whether you're validating a prototype, exporting a production mold, or looking for a molding partner who won't disappear when the project gets hard — we'd like to understand what you're building.
