High mix, low volume (HMLV) molding

High mix, low volume (HMLV) molding, is a strategic production strategy that offers businesses the flexibility to meet diverse customer needs while maintaining cost-effectiveness and efficiency. This process involves the production of a wide variety of products in smaller quantities, making it an ideal solution for manufacturing unique, complex items with specific quality requirements.

The flexibility inherent in high mix, low volume molding, allows for easy design changes, leading to improved customization of products. This increased responsiveness to customers not only enhances customer satisfaction but also provides a competitive edge in the market. Lower minimum order quantities and overhead costs make it a cost-effective choice.

At ThermoFab, we strike the perfect balance between precision and efficiency when it comes to our mold tooling. Mold tooling is fully customizable, which provides the flexibility to produce parts that match the exact specifications of your project. Our engineering team will review your part details and make any revisions for tooling optimization, while ensuring every detail aligns with your vision.

What sets our tooling apart? Our commitment to efficiency, with a lead time of 4-6 weeks, we ensure speed without compromising quality. We use P-20 steel for our injection mold tooling. Its durability and resilience to high temperatures and pressures is unmatched.

In addition, we can produce rapid prototypes for each production part design of your project.
