Lingpeng New Materials
Metal Injection Molding.
lpmim is the global-facing brand of Lingpeng New Materials Limited — a China-based manufacturer specializing in high-volume 304 stainless steel MIM components.
Born from a Market Imperative
Copper prices have more than doubled since 2020. For manufacturers of fire protection equipment, bathroom fixtures, and plumbing components — this isn't a cyclical fluctuation. It's a structural cost crisis.
We invested in the permanent solution: Metal Injection Molding of 304 stainless steel.
MIM enables stainless steel components with the same geometric complexity as cast copper parts — identical form, fit, and function — at 40–60% lower material cost with superior corrosion resistance.
Today, manufacturers in over 30 countries source 304 stainless MIM components from Lingpeng New Materials Limited. Our ISO 9001:2015 facility in China delivers 500,000+ parts monthly.
