Material Expertise

Proper injection molding plastic material selection is one of four pillars in our Manufacturing by Design process. Using the right plastic resins is critical for part performance and creates the best value. Our team knows the strengths, weaknesses and characteristics of most materials, so you never have to worry.

Making the proper injection molding plastic material selection is an important step in ensuring your project is a success. That is one of the reasons why we made it a main pillar in our Manufacturing by Design process. Regardless if you are using commodity resins or engineered resins, making the right plastic resins selection is critical for part performance and provides the best value. Our team of material experts have more than 60 years of industry experience and understand the strengths, weaknesses, and characteristics of most materials. Together we will help you make the right plastic material selection

Commodity Resins

Commodity resins are typically produced in high volumes and are less expensive and easier to process than engineered resins. Materials like Polyethylene resin or Polypropylene resin do not perform well in harsh environments due to poor mechanical, thermal, and chemical properties. Instead, they are often used for applications in the household appliance, construction, and packaging industries.

For those who might be new to the commodity resin selection process, our team of material experts are happy to help. Typically through a consultative discussion, we can work with you to determine the best material for your project. Below are a few of our frequently run prime, recycled, and re-processes commodity resins:

  • Polypropylene (PP)
  • Polyethylene (PE)
  • High Impact Polystyrene (HIPS)
  • Polyvinyl Chloride (PVC)
  • Acrylonitrile Butadiene Styrene (ABS)

Engineered resins

For processes that require a more durable material and solution, Engineered resins are a great option. Engineered resins are formulated to stand up to the harshest conditions due to the strength of the resin. Resins like Polyether Ether Ketone have such strong properties that they are often used in metal or wood replacement applications.

At Thogus, we have the experience to run even the most challenging materials and the know-how to find alternatives to suit your project. Below are a few of our frequently run engineered resins.

  • Nylon (PA6, PA66, and PA12)
  • Polyethylene Terephthalate (PET)
  • Polybutylene Terephthalate (PBT)
  • Polycarbonate (PC)
  • Tritan by Eastman (BPA free co-polyester)
  • Acetal (POM)
  • Polyether Ether Ketone (PEEK)
  • Polyvinylidene Difluoride (PVDF)
  • Polyether Imide (PEI)
  • Polyphenylene Sulfide (PPS)

Don’t see the combination you need?

While commodity and engineered resins are both great options, there are certain cases where custom resins are needed. For customers who require a more specialized material, we have the capability to provide creative solutions. As an injection molding company, we are able to compound custom resin formulations using a variety of resins and fillers to produce a product that will fit your needs. 

Combining custom resins provide the following benefits:

  • Radiation shielding
  • EFI/RMI shielding
  • High strength
  • Light weight
  • Noise reduction
  • Vibration dampening
  • Medical sterilization
