Molded Urethane Parts

Molded Dimensions Group is a manufacturer of molded polyurethane parts and components for custom applications. The urethane solutions we deliver can surmount the toughest performance and environmental conditions. We handle both high-speed, high-volume urethane pouring and lower volume, hand-poured jobs. This diversity is possible due to our wide range of urethane casting capabilities, which include:

  • Formulation of New Compounds: New formulas and molds designed and developed to supply parts that meet our customers’ most challenging standards of operation.
  • Diverse Parts and Solutions: Examples include high-wear and protection products like rollers, wheels, bumpers, glides, seals, couplings, and other industrial components.

Manufacturing Methods:

  • Open Cast Molding: This is the simplest of the molding methods. Polyurethane is smoothly poured into an open-top mold, or sometimes gently flowed up from the bottom of the mold. The product’s top face, or open face, usually undergoes a secondary machining operation in order to remove the over-pour.
  • Pressure Molding: This molding takes place in a sealed chamber. The chamber is held either at high pressure or in a vacuum. This method helps to eliminate air bubbles in the finished product.
  • Compression and Transfer Molding: Both of these molding methods use force to clamp together two halves of a mold. The applied pressure forces the polyurethane into all cavities of the mold. This molding produces products that have complex shapes, without the need for secondary machining operations.

After seeing users rave about the Stoltz brand for over a decade, JetBoatPilot decided to partner with Stoltz and create jetboat specific roller kits optimized to fit each unique hull. Stoltz rollers are a balanced blend of firm and soft. The urethanes used in forming the rollers are sufficiently firm to hold their shape over a lifetime of use, yet gentle on your boat's gelcoat. We chose Stoltz and Molded Dimensions Group because we wanted the best for our customers.

Great “people first” company! I have worked with them on many technical projects. Attention to detail, timely information, and accuracy are standard in development programs.
