High Performance Solutions 3 the Benefits of Machining Machined Parts Have Lower Stress Thermoplastic rod and plates for machining are stress-relieved. This reduces the possibility of part distortion. Molded parts may distort more easily. Machined Parts Have Consistent Properties Low Volume Requirements Are Most Easily Cost-Effectively Machined For small or intermediate lot sizes molds are neither necessary nor cost effective. Since thermoplastic stock shapes can be machined with standard metal-working tools youll find lower tooling costs when you machine to meet your design goals. Closer Tolerances Are Possible With Machined Parts When molded parts are made the orientation of material can cause variation in properties. Machined part properties are more consistent. Machined Parts Require No Draft Angle Draft is the taper required in mold cavities that allow the part to be ejected from the cavities. Therefore part surfaces will not be parallel or straight. Draft is not required with machined parts. Machined Parts Have No Weld Lines Machining is often the only way to hold tight tolerances. Molded parts cannot hold tight tolerances due to mold shrinkage and flow problems. Molded parts of annular ring shapes usually have weld lines which occur when the flow travels around the I.D. core and welds together. This weld area is the weakest area of the part. There is no critical weak point in a thermoplastic machined part. More Design Flexibility When You Machine Molded Parts Develop Skin Because there is no costly mold redesign needed changes in machined part size or material can be made quickly and easily. Molded mate
rials especially nylons have an amorphous quickly cooled surface or skin which may delaminate while the part is in service. Machined parts are uniform in crystalline structure and do not have skin problems. Faster Delivery Is Possible When You Machine Parts No extensive delays for first parts due to mold delivery. Some Parts Are Impractical To Mold Parts with multiple undercuts or adjacent thin and heavy sections are difficult to mold. Cross Sections Heavier Than 14 Cannot Be Molded Well Molding is not a good alternative for heavier cross sections since shrinkage will cause surface sinks depressions and internal voids. Sinks and voids do not occur during machining. Engineering Plastics Troubleshooting Difficulty Common Cause Difficulty Common Cause Drilling Tapered Hole 1. Incorrectly sharpened drill 2.
