I use I exploit A Metal Machining Company To Manufacture My Plastic Parts

Engineers and buyers often reach out to metal machining companies to produce plastic machined parts. They assume that the metal machinists use the identical processes as a plastic machining company, and therefore there is no significant difference. In reality, the 2 companies are worlds apart. This text reviews the three major the explanation why a company that machines metal should not be used to make plastic machined components.

air groupCutting fluids for each material are crucial:
Equipment used to machine metal – even when only used for metal occasionally – can contaminate parts with oil-based cutting fluids. Many plastics are also very sensitive to petroleum based cutting fluids and can degrade if they come into contact with these fluids. Additionally, many plastics are hygroscopic and will absorb the cutting oils. If the parts are being manufactured for FDA-approved uses or medical applications, they will not meet standards.

Metal fragments contaminate plastic parts:
It is difficult to adequately clean a machine that has been engaged on metals, especially if it has been working on stainless steel. This could lead to another contamination problem. If the plastic material is soft, residual metal fragments can become embedded in the parts.

Metal shops are experts in metal, not plastic:
Metal machining companies rarely have any in-depth knowledge of plastic materials, or more specifically, which material to use in an application. Plastic machinists know what plastics are best for any function, and might produce the part you need without the “trial-and-error” processes a metal machinist would use. A good plastic machining firm can have the fabric knowledge and the precise machining processes f&k petroleum 10 to consistently give f&k petroleum 10 you the best quality parts.
