Our in-house plastic material experts will help you decide on the most optimal material(s) for your application based on all factors of its usage. Additionally, we can look at your 3D models and drawings and recommend any changes necessary before parts are in production.

Does Tamshell produce parts in large quantities or bulk production runs?

Yes, however, depending on the size, material, and complexity of the part(s), lead times can vary significantly.

We also bag each part individually, in-house, and pack for shipping using stringent processes to keep your parts safe from damage en-route. If we send your parts for any secondary operations, we only send them to trusted partners who we know take extra care of your parts before they get back to us.

Other General Questions

Does Tamshell Machine Metal Materials?

Yes. We work with all machinable grades of Aluminum, Brass, and Bronze.

Does Tamshell produce Prototype parts?

In most instances, we can produce prototype parts which require CNC machining. If the prototype is still being designed, we can also give advice about the design and assist with material selection based on the application. We do not offer ‘Rapid Prototyping’ or 3D Printed prototypes.

Can Tamshell hold close tolerances?

We are capable of holding tolerances to +/- 0.0001” in most cases, with both of our CNC mills and lathes.

Does Tamshell sell or distribute stock material?

We are not a distributor or reseller of stock materials. We can however assist in material selection for machined parts to-be-produced at Tamshell. We work with several material distributors whom provide us with hundreds of grades of polymer, and soft metal materials. We always seek out the best pricing possible for our customers when seeking material.

Does Tamshell offer 3D Printing, Injection Molding, Rotomolding, or Polymer Extrusion?

We offer precision CNC Milling, Turning, and Swiss Screw Machining. Some components are better suited, and more cost-effective to be CNC machined, and others to be injection molded and/or 3D printed. When we review your Request for Quote, if we determine your part(s) might be better produced using methods other than CNC machining we are glad to help by providing recommendations for you.
