Dynatect’s Custom Molding Process

Dynatect provides full support through every step of the component life cycle: part design, material selection, process selection, prototyping, and production. It begins with the design collaboration and continues with first article inspections, dimensional validation and part traceability.

Step 1: Describe Your Application

Facing a wear, impact, chemical, or performance problem? Start by describing your application and operating environment.

Examples:

  • Wheels carrying loads over 500 lbs.
  • Components exposed to hot caustic washdowns.
  • Premature wear, cracking, or failure in service.
  • Noise, vibration, traction, or durability issues.

Step 2: Dynatect Provides Initial Design

Our engineers evaluate the root cause and performance requirements to recommend the right material and design.

We consider factors such as:

  • Abrasion and wear resistance
  • Chemical and oil exposure
  • Load capacity
  • Temperature extremes
  • Noise reduction and floor protection
  • Product life expectancy

Supporting services include:

  • Rapid prototyping
  • 3D printing and soft tooling
  • FEA and design analysis
  • Design for Manufacturability (DFM)

Step 3: Dynatect Recommends an Elastomer Formulation

Based on your application requirements, we select the elastomer formulation best suited to solve your performance challenge.

Material options include:

  • Polyurethane
  • Polyether
  • Polyester
  • Natural Rubber
  • Nitrile Rubber
  • SBR
  • Silicone
  • Engineering Plastics
  • Specialty Formulations

Step 4: Dynatect Chooses a Molding Process

Once the material is selected, we choose the production process that delivers the durability, consistency, and cost efficiency your application requires.

Manufacturing capabilities include:

  • Hot Cast Polyurethane
  • Ambient Cast Polyurethane
  • Injection Molding
  • Compression Molding
  • Transfer Molding
  • Reaction Injection Molding (RIM)
