Deciding between plastic manufacturing processes often leads to a discussion of urethane casting vs injection molding. Each of these methods has its advantages to meet a wide variety of production requirements. 

ARRK North America, Inc. offers both solutions to produce your plastic parts. Here is an introduction of what we provide, initiating a conversation on how to achieve your production goals. The best method is determined by the needs of the product and the market: diverse demands require different types of services to meet them.

Our urethane casting capabilities: 

  • Versatility
  • Speed to market 
  • Quality

Cast urethane parts provide a perfect way to work through iterations that best suit rapidly changing market demands in various industries including medical, consumer electronics, automotive, and robotics. 

We can produce lenses, keypads, and housings, even double-shot castings with an ABS-like substrate and urethane rubber overmold around it including cast in color and texture. Threaded inserts are molded into the parts as needed. 

Urethane casting services with ARRK can be colored or tinted to a wide range of color options matching PMS – Pantone, Federal Standard, RAL, or even provided color samples. Parts can have a smooth finish, high polish, or textured finish.

We have a wide range of additional finishing options we provide, depending on what is needed for the project:

  • Logo and Graphics Application
  • Spray Painting Texture
  • Electroforming Plate
  • Gold Color
  • Spin Line
  • Sputtering
  • Vacuum Metalize

What to expect when working with urethane casting for production parts?

With urethane casting, the mold is created quickly, providing a good low cost and quick turnaround for high value plastic parts. Besides, the versatility of urethane casting allows a wide range of specifications, a variety of rigidity, strength, flexibility, flame retardancy, and chemical resistance to name a few.

While a silicone mold wears out quickly it is vastly more cost-effective for very low volume and prototype plastic parts delivering production level quality and surface finishes. When speed to market is critical: urethane casting is a perfect solution.

Our injection molding capabilities

  • Short Run Prototype Molding
  • Low Volume and High Volume Production
  • All Certified Materials

We provide our injection molding service to some of the largest companies in the medical, consumer electronics, automotive, aerospace, and defense industries, manufacturing quality plastic parts. 

We have the ability to injection mold a full range of molding materials available from basic, filled, and specialty resins. Full production finishing services including the above and more are available as well for us to deliver ready for market parts.

What to expect when working with injection molding for production parts?

The biggest differentiator is the upfront costs and the time that it takes to create the mold. The molds are made of hardened steel or aluminum, making them highly resistant to heat and durable, able to withstand repetitive use over multiple productions runs with heavy high volume runs, without problems or change in the final product.

The time it takes to have the mold ready is because it is created through a variety of machining processes and finishing of the metal tool. The tools are able to withstand the heat and pressure involved in the process and comply with consistent quality standards. This investment in time provides a long-term solution to reducing the cost per part.

What is the preferred method for your production?

It all comes down to the different functions you need parts to achieve and production run volumes. We have an amazing, experienced team, that knows the trade and will consult with you providing the best advice to match your expectations, and production needs. 

We understand well the rapidly changing market demands and how that affects your business. ARRK North America, Inc. will work with you during every stage of the process to ensure we meet your plastic part needs and your production lead time goal.
