About CEX Casting
Qingdao Dechengxin Metal Products Co., Ltd. casts, heat treats, machines and tests aluminum parts across three bases in Jimo, Qingdao. Howard Ding, Sales Manager, is your contact from drawing to shipment.
Our squeeze casting and die casting factory
CEX Casting is the brand of Qingdao Dechengxin Metal Products Co., Ltd., the production company that owns the machines, holds the certificates and issues the invoice. Tooling, aluminum die casting, squeeze casting, zinc die casting, heat treatment, CNC machining, surface finishing, assembly and packing run in-house across three manufacturing bases in Jimo District, Qingdao.
Because tooling, casting and machining sit with one company, the casting allowance, the machining datum and the inspection plan are agreed together rather than across a supply chain. When you ask which machine will run your part, the answer is a machine type, tonnage and site, not a supplier name.
Who you deal with
Howard Ding is Sales Manager at CEX Casting and the first contact for every drawing and RFQ. He works directly with the factory team on A356-T6 squeeze casting, aluminum die casting and CNC machining, so engineers get direct answers on manufacturability, leak-tightness and inspection. Factory visits and live video audits can be arranged on request.
Each project has a named team: a sales manager, a sales assistant and a product manager, so the manufacturing discussion, the drawing questions and the delivery follow-up stay with people who know the part. CRM and ERP systems are used for order follow-up and delivery planning.

Why we developed squeeze casting
The squeeze casting route was developed in-house in response to defects seen repeatedly in conventional high-pressure die castings: internal porosity and shrinkage that lead to leaks, fractures, reduced service life and parts that cannot be welded.
The work covered the tooling and the machine together: feeding and exhaust in the mould, the hydraulic system and gas–liquid separation of the casting equipment, filling speed and pressure parameters, and alloy conditions.
Audit us before you order
Overseas customers can audit the factory on site, or by a scheduled live video walk-through of the casting, machining, heat-treatment and inspection areas. Compare what you see with the published equipment list and confirm machine type, tonnage and quantity on the floor.
What to check on the audit
- Match machines to the list: type, tonnage and quantity on the floor
- Ask what is running today: parts, alloys, customer industries
- Look at melt control: composition, pouring temperature, spectrometer result per heat
- Follow one real part from casting and heat treatment to packing records
- Open inspection records: first-article reports, X-ray images, leak-test results
- Check the tool shop: where tools are built and maintained, how changes are logged
- Trace a non-conformance: containment, record, customer notification
- Check calibration and traceability back to the melt and batch
- Environmental and safety systems: ISO 14001 and ISO 45001 activities on site
What we do not take on
Stating limits saves a round of quoting. A part inside these limits is still confirmed against the model and the annual quantity.
- Parts too heavy for our largest press (checked per drawing)
- Parts needing more than 1,100 t of clamping force
- Envelopes beyond 1.2 × 0.8 m
- Castings for aerospace, medical, food-contact or pressure-vessel applications
- Sand, gravity or low-pressure die casting: we run die casting, squeeze casting and zinc die casting only

Environmental and safety management
The casting workshop uses a gas collection system that captures exhaust from casting and centralised melting and pipes it continuously to treatment facilities outside the workshop. Environmental management and occupational health and safety are certified to ISO 14001:2015 and ISO 45001:2018.
