Depois da fundição, parts typically require a range of post-processing operations to meet final delivery specifications. We offer comprehensive post-processing and secondary services – including de burring, acabamento superficial, tapping/drilling, and heat treatment – ensuring that every casting meets customer requirements for function, aparência, e desempenho de montagem.
What is Post-Processing？
Post-processing refers to all auxiliary operations required after a casting is ejected from the die casting machine, before it becomes a deliverable finished part. These operations directly impact the final quality, aparência, assembly precision, and service life of the product.
Our Post-Processing Services
EU. De burring & Surface Preparation
- Manual deburring (precision treatment for complex areas)
- Vibratory tumbling (batch removal of burrs and sharp edges)
- Jateamento de areia (surface roughness improvement, acabamento fosco uniforme)
- Tiro (oxide layer removal, surface strengthening)
- Barrel tumbling (ideal for high-volume small parts)
II. Usinagem (see CNC Machining page)
- Perfuração, tocando, alargamento
- Fresagem, girando
- Perfuração profunda
III. Acabamento de Superfície (see Surface Finishing page)
- Anodizando (clear/dyed/hard coat)
- Revestimento em pó (various colors and textures)
- Liquid painting (gloss/matte)
- Galvanoplastia (zinco, níquel, cromo, etc.)
- Chemical conversion coatings (passivação, phosphating)
4. Tratamento térmico
- Stress-relief annealing (eliminates internal stress, stabilizes dimensions)
- T5/T6 solution and aging treatment (enhances mechanical properties)
- Process optimization tailored to different materials
V. Conjunto & Embalagem
- Parts cleaning (ultrasonic cleaning)
- Conjunto (threaded insert installation, seal ring assembly, etc.)
- Teste funcional (teste de vazamento, inspeção dimensional)
- Professional packaging (rust protection + custom packaging solutions)
