We are an innovative model and prototype shop serving the designer or engineer who wants exceptional quality, accuracy, and completeness at a competitive price. No project is too large or too small. We create prototypes in every size imaginable, from the tiniest electrical connector to large scale tractor parts.

Our highly experienced and talented staff will deliver your project on time, on budget, and on-target per your schedule. If you require quick turn around with guaranteed quality, we’re your team. You will find our prices very competitive and our quality is second to none.

Below is a brief introduction to our main departments


CNC machining allows Centerline to reduce your lead time to as little as one day. CNC prototypes can be cut out of almost any material, and Centerline’s post machining and finishing will provide you with the prototype or model you need to move on with your product testing.


Whatever you need; Centerline can create your mold and cast your product. Utilizing a wide array of both casting and molding materials, Centerline will custom build your product to your exact specifications. Centerline creates; polyurethane, silicon, metal, and color casts, as well as; RTV, silicon, rubber, delrin, and ABS molds.

Finishing & Painting

The final step in the completion of your vision. Centerline hand finishes and color matches your model or prototype to your exact specifications. With the ability to finish in many materials, texture to any specification, and paint to perfect your project; Centerline’s finishing department is second to none.


Stereolithography (SLA or SL; also known as stereolithography apparatus, optical fabrication, photo-solidification, or resin printing) is a form of 3-D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photopolymerization, a process by which light causes chains of molecules to link together, forming polymers.[1] Those polymers then make up the body of a three-dimensional solid. Research in the area had been conducted during the 1970s, but the term was coined by Charles (Chuck) W. Hull in 1986 when he patented the process. He then set up 3D Systems Inc to commercialize his patent. – From Wikipedia


Vacuum Forming is the leading Plastic Thermoforming process in which sheet plastic is heated and formed over a mold by removing air from the area between the mold surface and the sheet. Molds can be created from aluminum, wood, or epoxy. The mold type is only dependent on the finished product design requirements.


CAD is used to design and develop products. CAD is used throughout the engineering process from conceptual design and layout, through detailed engineering and analysis of components to definition of manufacturing methods. Let Centerline’s CAD experts work with you to perfect your design.
