Surgical Saftey Scalpel Handle

Feature:

Material: 17-4PH, also we call them X5CrNiCuNb16-4, AISI 630, NF S94-090, UNS S17400 or sus 630. It have special performance compared with other stainless steel like SUS316L, because 17-4Ph material could have hardness after age hardening 40-44HRC. Then it should be more wearable and not easy deformed in annealed condition. But we could quote you the same price to improve the item quality.

Tolerances: for hole less than 2mm, polished, could reach h8. hole more than 2mm, cold drawn, polished, could promise ISO h7. Surface finish Ra 0.4(N5).

Surface treatment: vibrate grinding or manual polishing. For this MIM surgical safety scalpel handle products, the surface is the most important because they are all exposed and skin-contactable surface. Any rusty and irregularity are not allowed.

Density ≥7.75g/cm3. This 17-4PH material for MIM scalpel handles by metal injection moulding process is standard and have its own mechanical property. If you need any other requirements, we could adjust this because our engineers is very professional on this we have laboratory to study PIM material.

Advantage: The surgical scalpels could be final shaped for one time and do not need other process. If very precious tolerance, the holes of smart and electric spring bolt could be drilled and CNC machining. Often we could promise hole 4mm with+-0.03mm tolerance with this process.

It is absolutely right if you choose our MIM technology:

Compared with traditional powder metallurgy, CNC machining and investment casting, MIM technology has the following advantages:

1, High precision: the size precision for one shot process can reach +/- 0.1~0.5%. For some higher precision requirement, can machined by CNC.

2, Various materials: MIM parts can be made of iron, stainless steel, steel, hard alloys etc..

3, Low cost: to make complex shape and mass quantity parts, MIM can save quite a lot of cost.

4, Minimizes scrap losses by typically using more than 97% of the starting raw material.

5, Sustainable manufacturing - Green technology.
