Fabrication FAQs

Do you support prototypes and short-run production?

Yes — we support one-off prototypes through repeat short-run production, depending on material and requirements.

What do you need to provide a quote?

For the fastest quote, include material (if known), thickness/size, quantity, timeline, and a drawing (PDF/CAD) if available.

Do you offer cut-to-size services?

Yes — we can cut plastics to size based on your specifications and application requirements.

Can you hold tight tolerances?

Yes — we regularly support close-tolerance work. Tolerances depend on part geometry, material, and process.

What plastics do you fabricate most often?

We fabricate a wide range of plastics based on application needs, including chemical resistance, wear, impact, and temperature performance.

Do you provide CAD/CAM support?

Yes — we can support CAD/CAM needs depending on project scope and the information provided.

Do you ship nationwide and offer local pickup?

Yes — we serve customers across Connecticut and ship nationwide. Local pickup may be available—contact us to confirm.

How fast can you turn parts around?

Lead times depend on material availability and scope, but we prioritize responsive quoting and fast turnaround for many prototype and short-run jobs.
