4 Tips to Consider When Choosing Injection Molding Companies in the U.S.

When choosing an injection molding company in the U.S., business owners should consider a variety of factors to ensure that their production needs are met, specially that the market is expected to reach USD 266.1 billion by 2030, as per Precedence Research. With this growth, I believe choosing the best one is crucial. So, here are 4 tips to consider:

  • ISO 13845: Ensure that the injection molding company has the technical capabilities to handle your product’s requirements. For example, if your products require components for medical devices, choose a company that holds ISO 13485. This certification ensures the company adheres to internationally recognized standards, which demand the highest level of quality control and production consistency.
  • 4-8 Weeks Lead Times: Lead times are crucial in planning and maintaining your production schedule. By confirming that potential partners can meet a lead time of 4 to 8 weeks, you can align their capabilities with your market commitments and ensure continuous product availability without disruptions.
  • Prototyping Capabilities: Early design support and prototyping capabilities are essential for resolving potential issues before full-scale production. For example, if you need rush project prototype, companies that offer comprehensive prototyping services can help speed up the development process, enabling quicker market entry and the ability to adapt rapidly to market or design changes.
  • Resins Material Expertise: The choice of material impacts every aspect of an injection molded component, from its strength and flexibility to its appearance. Expertise in various resins or composites is crucial for achieving the desired product characteristics. Ensure the company you choose has deep knowledge of the specific materials needed for your products to optimize performance and functionality.

The table below outlines various resins commonly used in injection molding, highlighting their key properties and applications:

Resin Type Strengths Weaknesses Best Used For Considerations for Selection
ABS (Acrylonitrile Butadiene Styrene) High impact resistance, toughness Poor weatherability, can warp with heat Automotive parts, electronic housings Ideal for products requiring toughness and dimensional stability
Polypropylene (PP) Lightweight, good chemical resistance Poor UV resistance, high thermal expansion Food containers, medical devices Choose for applications needing chemical resistance and flexibility
Polycarbonate (PC) Very high impact strength, transparent Can scratch easily, expensive Bullet-proof glass, eyewear lenses Best for applications requiring transparency and high durability
Nylon (Polyamide) High wear resistance, good thermal properties Absorbs moisture which can affect dimensions Gears, automotive components Suitable for parts subjected to wear and requiring high strength
High-Density Polyethylene (HDPE) High strength-to-density ratio, resistant to impact Poor weathering resistance, warps under load Containers, plastic bottles Useful for high-volume products needing impact resistance and flexibility
