Molding

Extensive Investment

Jasper Rubber Products, Inc., continues to invest extensively in the most responsive molding equipment. Our ongoing commitment to excellence enables us to further our leadership position and increase our capacity. Turn to us for product manufacturing that requires injection molding, compression molding, or transfer molding—you’ll receive custom molded solutions precisely configured to complex specifications.

Our Molded Offerings

Injection molding produces exacting compliance to dimensional tolerances and reliably high quality for your products and components. And it’s a key production process here at Jasper Rubber.

Our investment to injection molding technology enables us to produce your rubber, plastic, or elastomer products and components with excellent compliance to even the most exacting specs. Plus, our fast turnaround time yields higher volume runs while lowering unit costs.

Our Capabilities:

  • Injection presses from 100tn–800tn (90,718.50kg–725,748.00kg), several of which equipped with shuttle tables for insert and over-molded parts
  • Suited for tight tolerances, complex geometries, and parts where flash and secondary operations come out of cost
  • Insert molding and bonded rubber-to-metal/plastic assemblies
  • Cryogenic deflashing and automated camera inspection
  • Production Part Approval Process (PPAP)–capable launches with full process documentation

Valve gate injection molding gives positive control over fill and gate closures. That means cleaner gate vestiges, balanced filling across cavities, less scrap on cosmetic parts, and fewer secondary trim operations.

Our Capabilities:

  • Cosmetic and close-tolerance parts with gate witness considerations
  • Balanced, multi-cavity fills for consistent part-to-part properties

As a preferred manufacturing method for several components and materials, compression molding is used frequently at Jasper Rubber. It’s ideal for larger parts, less precise or exacting dimensional tolerances, and lower-volume runs. Plus, tooling for this process is cost effective and produces less waste material.

When you trust Jasper Rubber to manufacture your compression molded components, you benefit from our ongoing investment in equipment, technology, and the expert skills of our production team members.

Our Capabilities:

  • Deep compression capacity, from multi-station presses for small parts through large-platen presses for heavy sections
  • Correct tooling economics, part sizes, and compound behaviors for favoring compression over injection
  • Shuttle presses with 32.00″ x 32.00″ (812.80mm x 812.80mm) platens in 700tn (635,029.00kg) class
  • Roughly 100 openings across multi-station presses for small parts
  • Autoclave curing for extruded and formed profiles

Jasper Rubber also provides plastic injection molding with a variety of capabilities.

Our Capabilities:

  • Thermoplastic injection molding from 80tn–500tn (80,000.00kg–500,000.00kg), with a 220tn–250tn (220,000.00kg–250,000.00kg) sweet spot (rubber and plastic components for same assembly can be built, matched, and shipped from one plant)
  • Standard and underhood-rated thermoplastics, including but not limited to polypropylene (PP), polyethylene (PE), nylon (PA), glass-filled nylon, ULTEM® (PEI), and equivalent automotive-grade polymers
  • Profile extrusion of thermoplastic elastomers, including Santoprene™ and similar thermoplastic vulcanizate (TPV) grades

Similar to compression molding, transfer molding is a very efficient and popular option at Jasper Rubber, especially for our customers seeking proprietary product runs. During this process, a transfer system located on top of the mold feeds rubber or elastomer material into mold cavities as the press is closed, resulting in excellent uniformity among mold cavities.

It’s ideal for both intricate parts as well as components not required to meet too exacting of tolerances. It’s also great for both lower- and higher-volume production runs.

Just like our other molding capabilities, Jasper Rubber continues to invest in expanding and developing our transfer molding manufacturing equipment, technology, and production expertise.

Ask about our comprehensive deflashing processes.

Our molding expertise has earned us a solid position as a renowned US-based rubber manufacturer—but our attention to excellence and detail does not stop at production.

At Jasper Rubber, our inline, nonabrasive cryogenic deflashing system and stringent inspection techniques complete our first-rate molding production process. It protects the integrity of your product while cleanly removing flash from even the most complex configurations. It’s also another way we thoroughly care for your product.
