Which Engineered Plastics Can Jaco Products Machine, Mold, or Stamp?

Updated

Jaco Products works with three separate material sets, one for each of its core processes: CNC machining, injection molding, and stamping/die cutting. If your part is already designed around a specific resin, the fastest way to check fit is to match your material to the process list below. Note that the lists are process-specific — a material available for machining is not automatically offered for molding, and vice versa.

CNC Machining Materials

Jaco's machining capabilities cover complex parts and high-tolerance work, including 5-axis CNC plastic machining, from prototype through high-volume production.

Material Typical use in plastic parts
Delrin (acetal) Precision mechanical parts needing low friction and dimensional stability
Nylon (6/6, 6/12) Wear parts, bushings, and components needing toughness
HDPE Chemical-resistant and low-moisture-absorption parts
FR-4 / G-10 Rigid, electrically insulating structural components
PEEK High-temperature and high-strength applications
Polycarbonate (Lexan) Impact-resistant transparent or structural parts
Acrylic Clear covers, guards, and display components
Ultem (PEI) Heat-resistant, dimensionally stable parts for demanding environments
UHMWPE Low-friction wear strips and guides

If your part requires tight tolerances or a one-off/prototype quantity, this is the list to check first.

Injection Molding Materials

Molding is the route for higher-volume production of complex parts. Jaco's molding material set includes:

  • ABS — general-purpose housings and covers
  • Acetal (Celcon, Delrin) — molded precision mechanical parts
  • Nylon 6/6 and glass-filled nylon — strength and stiffness where needed
  • Polypropylene — cost-effective, chemical-resistant parts
  • HDPE — durable, low-absorption components
  • Polycarbonate — impact-resistant parts
  • PC/ABS alloy — a balance of impact strength and processability
  • Ultem — high-temperature molded components
  • PBT (Valox, Crastin) — electrical and structural parts
  • Polystyrene — rigid, low-cost components
  • Thermoplastic elastomers (Isoplast, Santoprene) — flexible or soft-touch parts
  • Acrylic — clear molded components

A practical check: if your design calls for glass-filled nylon or a PC/ABS alloy, molding is the listed process; if it calls for G-10 or FR-4, those appear only under machining.

Stamping and Die-Cutting Materials

For thin-sheet and insulating components, Jaco lists these materials:

  • Nomex® — heat-resistant electrical insulation
  • Mylar® polyester — thin insulating and barrier films
  • Polyester — general sheet components
  • Kapton® — high-temperature flexible insulation
  • Vulcanized fiber — rigid, tough sheet parts

Stamping/die cutting suits flat parts such as insulation barriers, gaskets, and shims rather than three-dimensional machined or molded geometry.

How to Match Your Part to a Process

Use these three questions in order:

  1. Is the part flat and thin? Start with stamping/die cutting and check the Nomex/Mylar/Kapton/vulcanized fiber list.
  2. Is it a 3D part in low-to-moderate quantity, or does it need very tight tolerances? Check the CNC machining list, especially if your material is PEEK, Ultem, G-10/FR-4, or UHMWPE.
  3. Is it a 3D part headed for volume production? Check the injection molding list; if your resin appears only in the machining list, expect a material or process conversation rather than a direct match.

Jaco also notes that it serves industries including electronics, medical devices, aerospace, automotive, food and safety (FDA-compliant components), healthcare and beauty, industrial equipment, and recreation and toys — useful context if your part must meet sector-specific material expectations.

For anything not on these lists, or where a part spans two processes (for example, a machined prototype later moved to molding), request a quote with your drawing and resin specification so the material and process can be confirmed together.
