Why Plastic Machining
There are many different choices when it comes to plastic machining. Here are some key factors that give Tamshell an advantage over other metal machine shops and injection molding companies.
Plastic Shop vs. Metal Shop
- Over 25 years in plastic machining experience
- Understanding of material characteristics:- Plastics bend, warp, shrink, and expand during the machining process.
- Temperature controlled facility:- Extremely important with temperature sensitive materials
- No metal contaminates:- Some industries require that there are no metal contaminates
- Specialized tooling in house
- Special material pricing from plastic vendors:- All we buy is plastic material so we have a competitive edge on purchasing plastic
- We only machine plastic
When deciding between machining and molding a part please keep these key points in mind, not all parts need to be molded to save cost. Please contact us if you are not sure of what process you should use to produce your plastic components.
Plastic Machining vs. Injection Molding
- Ability to machine tighter tolerances:- Some injection molders have issues with tight tolerances
- No extra tooling costs:- You don’t have to pay for a tool or maintenance when the tool goes bad
- Low volume quantities:- Injection molding is very costly when it comes to low volume runs
- Competitive pricing on production runs:- Machining can be competitive in high production runs based on tolerances, quantities, design and material
- All plastics can be machined
- No need for secondary operations:- On some injection molded parts, molders are unable to produce features required on the drawing
- Engineering changes are easily accommodated with machined components:- Engineering changes require tooling changes when it comes to injection molding
- No quantity variance on orders:- What we quote is what you get. Molders generally have an attrition rate when ordering molded parts
