Our Process
Send us your drawings, specifications or application requirements.
Our engineers evaluate feasibility and suggest optimized solutions.
Receive a detailed quote with pricing, lead time and specifications.
Prototype samples are produced for testing and confirmation.
Mass production with strict quality control at every stage.
Secure packaging, on-time shipment and full after-sales support.
Our quality system is built around prevention, not just detection. From feedstock and mold-flow control through sintering shrinkage management to final CMM verification, every stage of the MIM process is monitored and documented.
Critical dimensions are checked after sintering to confirm shrinkage stayed within tolerance, with full dimensional reports provided for every order.
Certified to ISO 9001, ISO 14001, and ISO 45001 through Tongyong Hardware, our China manufacturing entity, within the scope stated on its certificates.
Material certificates, sintering process records, and first-article inspection reports are provided for full traceability from feedstock to finished part.
Dedicated engineers review wall thickness, gate placement, and shrinkage allowances during DFM, helping avoid warping and short-shot issues before tooling begins.

Find answers to common questions about our Metal Injection Molding (MIM) services.
MIM becomes more cost-effective as volume increases, since tooling cost spreads across more parts. For prototyping, CNC is typically more practical.
Small, complex parts — a few grams up to around 100 grams — with features like internal threads or thin walls.
MIM suits small, complex parts needing tight tolerances; die casting suits larger, simpler parts at very high volumes.
Yes. We review part geometry and injection mold design early to identify potential issues before tooling begins.
For prototyping and design validation, we can support faster turnaround options before full production tooling.
Yes. We support low volume injection molding for smaller production runs, in addition to medium-to-high volume production.
Injection molding cost is influenced by part complexity, material, tooling design, and production volume. A detailed quote is provided based on your specific drawing and requirements.
