Die-cast housings
Focus on release agent, exposed porosity, cavity drainage, threads and masking of mating surfaces.
MAGNESIUM SURFACE ENGINEERING
Surface Treatment for Automotive Magnesium Parts
A project path from drawing review to sample, pilot lot and production for die-cast oil, cavities, threads, mating surfaces, edges and batch consistency.
Automotive project path
Automotive work needs clear inputs, sample records and change boundaries. The workflow below describes our approach without disclosing customer identities or confidential parameters.
| Stage | Input | Engineering action | Output |
|---|---|---|---|
| Document review | Drawing, alloy, use and volume | Identify rack, masking, cavity and assembly risks | Sample plan and open-point list |
| Sample validation | Representative parts and targets | Compare passivation and e-coating routes | Appearance and test records |
| Pilot lot | Packing, takt and inspection plan | Confirm stability, yield and delivery | Production process limits |
| Production | Agreed technical specification | Process control and corrective action | Traceable batch delivery |
Structural brackets
Focus on rack strength, edge coverage, distortion risk and repeatable batch loading.
Lightweight components
Select the finish route around environment, appearance, conductivity, corrosion and assembly requirements.
FREQUENTLY ASKED QUESTIONS
Technical FAQs
Process parameters, test methods and acceptance criteria are confirmed against representative samples, drawings and the agreed quality specification.
Can you quote an automotive part from the drawing?
We can provide an initial review. A firm proposal also needs alloy, weight or area, specification, monthly volume, packing and delivery terms.
Can threads and mating surfaces be protected?
Dedicated masking and racking can be evaluated against the drawing and representative samples.
How is batch consistency controlled?
Through defined incoming conditions, process windows, inspection criteria, reference samples and corrective-action rules.
