Custom Plastic Parts

Whatever the shape, size, quantity, or material needed for your next plastics project, Jaco Products can help. We fabricate plastics that other companies won’t touch, and our 5-axis equipment allows us to cut shapes that others cannot.

Design your part

Custom plastic injection molding begins with the design of your part. We collaborate with our customers on producing designs that are both effective and cost-efficient to make. Small tweaks at the design stage can make all the difference when the part is manufactured. Help us to help you by bringing your design to us in the early stages so we can make recommendations.

Right first time

Designing molds is expensive and time consuming, so getting it right first time is important. Once the mold is set up to your specifications, the molding process is quick and efficient, and money can be saved with an intelligent approach to mold design at the beginning of a project.

A combined approach

After the initial setup, plastic injection molding is a quick, low-waste process. At Jaco we use a combination of injection molding and machining to fabricate complex and difficult-to-manufacture parts. Our operation is set up to machine complicated plastic shapes that other shops won’t touch.

Reduce costs

Our state-of-the-art machinery can rout, mill, and turn to extremely low tolerances. CNC machining cuts down on labor costs and significantly reduces the overall cost of producing a part.

Machining Different Plastics


Delrin is supplied in sheets and bars for the purpose of milling and turning and supplied in granular form for melting and placing in molds. It has excellent dimensional stability and is easy to cut to very low tolerances. It is high strength and is resistant to chemicals. Delrin is an excellent dielectric. It can be difficult to use adhesives with Delrin, however, but in our experience, it is possible to manufacture complete parts from a single mold and by using an intelligent approach to CNC machining the material.


Ultem is a high-performance thermoplastic that has excellent heat and flame resistance. It is supplied in the form of rods, sheets, tube, or film. Glass-reinforced Ultem requires coolant to machine, as well as hardened metal tooling. Ultem is a high-performance plastic that is stiff, strong, and relatively easy to machine. Some grades of Ultem are more difficult to machine because of their stiffness—specifically glass reinforced Ultem—but Jaco Products has the experience, knowledge, and equipment to tackle any Ultem project.


PEEK can be used as a reliable alternative for metals because of its stiffness, chemical resistance, low moisture absorption, and resistance to biodegradation. PEEK requires annealing before machining but can be machined to a high accuracy to very tight tolerances. You can find PEEK in aerospace, automotive, chemical, electronics, energy, and healthcare industries.


Nylon can be difficult to machine because it deforms easily from being held in position but offers extremely tight tolerances and high strength and dimensional stability. Jaco Products has plenty of experience machining nylon and we are happy to work with this material to produce your part.

Costs Involved with Manufacturing Custom Plastic Parts

The production of custom plastic parts allows for incredible versatility in color, shape, materials, additives, and finishes, making molding a versatile approach to producing your parts. The flexibility in design, combined with low waste—scrap can easily be recycled—allows for a simple and easy-to-implement process. Molds can be expensive to produce, however, as can ancillary products such as mold and platen insulation. But once the setup is complete, the molding process is inexpensive, sustainable, and efficient.
