We specialize in Plastics, High-Performance Polymers, Aluminum Alloys, Brass, and Bronze.

We cover all of the bases. From general purpose materials such as PVC, to thermoplastic polymers like Ultem®, to 6061 Aluminum and all grades, shapes, and fillers in-between.

Ultem Parts

Not only are we the experts at machining these high-performance plastic materials, but we are also referred to as a sourcing and selection specialists.

If you do not know G-10 from G-11, or the wear-resistance levels of Nylatron®, or the maximum temperature range of Polysulfone… Not to worry because we certainly do. We have been assisting in Material Selection for our customers for more than thirty-five years. However, if you do know all the characteristics of high-performance polymers, then you can trust Tamshell to machine your precision components or parts with the material you need and the quality you would expect.

Plastic Materials

There is no doubt in our minds that high-performance plastics continue to prove their never-ending value. The continual innovations and improvements in polymers have allowed all industries to manufacture goods that are lighter in weight, can withstand extreme temperatures, provide maximum fluid control, and allow for structural and bearing and wear all at a lower cost than their heavy metallic counterparts. We are “Experts” with plastics because we have carefully followed the trends, go through the trials, and know what works and what does not for just about any application. Moreover having 35 years in the CNC precision plastic fabrication business has given us the means to do so.

Common plastic materials are: ABS, Acetal, Acrylic, Celazole®, Delrin®, Duratron®, Ertalyte®, Fluorosint®, FR4/G10, G11, HDPE, Ketron®, Kydex®, Kynar®, LDPE, Lexan®, Noryl™, Nylatron®, Nylon, PCTFE, PEEK, PEI, PET, Polycarbonate (PC), Polyethylene (PE), Polypropylene (PP), Polystyrene (PS), PPSU, PSU, PTFE, PVC, PVDF, Radel®, Rulon®, TECAPEEK™, TECASINT™ PI, TECATOR™ PAI, TECATRON™, Teflon®, Tefzel®, Torlon® PAI, UHMW, Ultem®, Vespel® PA, Zytel®

Soft Metals

In the industries we serve, there are applications that require the stability, electrical conductivity, and strength that only certain alloys and metals can provide. Although these materials tend to weigh substantially more than plastics, and might not have the same resistance to chemicals and wear, they still fit the bill for many uses more optimally than plastic materials.

Soft Metal Materials

In addition to plastics, Tamshell is a precision Soft Metal machining center which focuses on up to 5th axis and tight tolerance turned Aluminum Alloys, Brass, Bronze, and other soft metals machining. We supply soft metal parts to Aerospace, Electrical, Semiconductor, and other industries who count on our quality with every purchase order.
