The casting quality standards:

] casting classification, grading and the chemical composition, mechanical properties, surface quality, internal quality compliance HB963-90, HB5312-85, HB5430-89, HB5480-91, RZLB1-86 and other standard of.

The production cycle

After the common casting products in the contract after the entry into force of 4 to 6 weeks to complete the mold production and delivery of qualified samples. Special products separately.

Note the order of investment castings:

] to do a good job in the parts of the structure process of review work (higher dimensional accuracy and surface roughness is fine, the shape of the casting more and more complex, the casting cushion more hours and even more so), so as to make casting design and material selection more reasonable, easy guarantee of the quality of casting, reduce casting production cost budget, avoid because of design problems caused delays the production time and pay more costs. (in the course of the problem, contact us, negotiate with our foundry Engineers).
