Gasket Express can offer machined plastic products as an alternative to molding.
INFORMATION
In addition to lower volumes and prototypes being available, other advantages of machines plastic products over molding include:
- Certain parts are difficult to mold due to size or certain thread patterns.
- Materials can be used that can not be molded
- Lower tooling costs than molding
- Machined parts can be produced with lower residual component stresses and more consistent properties throughout the produced part
- Closer tolerances may be achieved with machining
- More flexibility designing parts
- Changes are easier with machining
- Better lead times
- No draft angles for machined parts
- Machined parts will not have some of the undesirable attributes of molded parts (gate scars, weld lines, parting lines, ejector marks, flash or “skin” effects, etc.)
