Precision starts
with engineering.
Turn your drawing into a practical manufacturing plan.
Our engineering coordination connects English-language drawings, material specifications and geometric dimensioning and tolerancing (GD&T) with the production resources of our partner factories.
Design for manufacturability (DFM) review and mold-flow simulation inform die-casting mold design before tooling begins. Complex thin walls, high air-tightness housings and precision assembly features receive particular attention.
Explore engineering support ↗
- 01
Understand the part
Review the alloy, geometry, critical dimensions and application requirements.
- 02
Assess the process
Evaluate filling, tooling, machining and inspection needs before production.
- 03
Confirm the route
Agree the drawing revision, sample approval and quality criteria.
Crafted with care.
Checked with precision.
Toolmaking, casting, finishing and inspection form one connected route, with the process selected around your component.
From mold to finished part.
CNC machining centers, electrical discharge machining (EDM), wire EDM, high-speed engraving and mold polishing support precision tooling and mold trials.
Our partner resources include cold-chamber machines for aluminum alloy die casting, hot-chamber machines for zinc alloy die casting and dedicated magnesium alloy die-casting equipment. High-pressure die casting (HPDC), with vacuum assistance where required, is supported by die-temperature control, automated release-agent spraying and robotic extraction.
CNC machining, turning, drilling and tapping prepare critical features. Deburring, polishing, blasting and surface treatment complete the agreed route.
Finishes include plating, painting, powder coating, anodizing, passivation, brushing and high-gloss polishing. Suitability is reviewed for the alloy, casting condition and performance requirements.
Check what matters.
- Dimensions & fit
Coordinate measuring machines (CMMs), optical profile projectors and final inspection stations.
- Material & performance
Optical emission spectrometry for alloy composition, hardness testing and high/low-temperature testing.
- Surface & protection
Salt-spray testing and color measurement for agreed finish requirements.
Evidence for your project.
Partner quality control follows ISO 9001 principles. Inspection, testing and documentation are agreed for each order.
SGS testing and material reports can be coordinated within the agreed scope. Automotive projects can include IATF 16949 quality-system requirements and PPAP Level 3 submissions. Applicable partner certificates, report availability and acceptance criteria are confirmed before commitment.

every stage.
A small sample order. A repeat production run. A change in requirements.
Our dual supply-chain approach combines precision manufacturing resources with scalable production capacity, balancing quality, lead time and cost around your project.
- 01 / VALIDATE
Samples
Tooling trials and small-batch sample production to your drawing, material and quantity requirements.
- 02 / REFINE
Small batches
Agreed manufacturing steps support low-volume orders and feedback before wider production.
- 03 / REPEAT
Volume production
Coordinated casting, secondary operations and quality checks support repeat export orders.
Custom to your requirements
OEM/ODM projects, drawing-based manufacture and processing of customer-supplied materials, subject to technical review.
Clear communication
Progress updates, early risk identification and documented engineering changes keep the latest requirements traceable.
Open to verification
Video factory tours, on-site factory audits and pre-shipment inspection can be arranged with the relevant partner.
Connected
manufacturing resources.
Shanghai Qinghui Industrial Co., Ltd. coordinates long-term partner die-casting factories across these manufacturing clusters. Their resources connect mold development, casting, secondary operations, inspection and export delivery.
Projects serve automotive, new energy, industrial electrical products, smart equipment and high-end tools, alongside machinery, appliances, lighting and communications hardware.
Tooling
Design → machining → mold trials → sample approval
Production
Die casting → deburring → CNC machining → finishing
Delivery
Inspection → packing → export documentation → shipment
