INJECTION MOLDING
6 Early DFM Decisions That Define Injection Molding Success
Too often, injection molding programs encounter preventable delays, cost overruns, and quality risks because critical decisions are made too late.
In this feature, Mike Fuller, Director of Technical Solutions, shares how Velosity’s Design for Manufacturing (DFM) approach shifts that paradigm by bringing engineering insight to the earliest stages of design, where it has the greatest impact. Discover the six essential DFM decisions that drive successful part development, from parting line strategy and material selection to gating, draft, and wall section optimization. By aligning design intent with manufacturing realities early, teams can accelerate validation, improve part quality, and reduce overall program risk.
Explore how Velosity’s DFM expertise helps med tech innovators launch faster, reduce risk, and achieve first-time-right production outcomes.
INJECTION MOLDING
Two-shot Injection Molding
Two-shot injection molding, also known as double-shot molding, is an advanced technique that enables the seamless integration of two materials or colors in a single shot. This process eliminates the need for secondary assembly, reduces cycle times, and ensures consistent, high-quality performance.
At Velosity, we specialize in high-volume production, leveraging state-of-the-art injection molding machines to produce precision-engineered components. Our two-shot injection molding capabilities are particularly well-suited for complex applications in industries such as medical and defense. With extensive expertise in two-shot molding technology, we consistently deliver superior results.
INJECTION MOLDING
Cleanroom
Many of our customers rely on us for specialized products, especially those that require manufacturing and assembly in a cleanroom environment. Velosity excels in supporting all your product needs, including medical device contract manufacturing, leveraging our multiple ISO Class 7 & Class 8 cleanrooms.
INJECTION MOLDING
Thermoplastics
& Elastomers
Thermoplastic Elastomers (TPEs) are indispensable materials used across many industries, from medical devices to defense and aerospace parts. The combined advantages of the mechanical elasticity of elastomers and the ease of processing thermoplastics have made TPEs an ideal material.
Velosity knows TPEs are cost-effective and offer high flexibility in the design and manufacturing process. TPEs are easily processed by conventional injection molding, blow molding, and extrusion processing while maintaining their quality.

Frequently Asked Questions
What Is Injection Molding Contract Manufacturing?
Injection molding contract manufacturing means outsourcing your plastic parts production, from tooling to finished, inspected parts, to a dedicated manufacturer. A contract partner, like Velosity, provides dedicated machine capacity, consistent quality, and end-to-end program management so you can focus on your product instead of your production line.
Why Work With an Injection Molding Contract Manufacturer?
Partnering with an injection molding contract manufacturer gives you access to manufacturing expertise, production capacity, and quality systems without investing in your own molding operation. Velosity manages tooling, production, inspection, and supply chain coordination so your team can focus on product development, innovation, and growth while maintaining reliable part quality and delivery.
What Should I Look for in a Plastic Injection Mold Company?
Look for a partner that offers engineering support, in-house tooling, a broad selection of materials, robust quality systems, and the ability to scale production from prototyping through high-volume manufacturing. Experience in your industry, program management, and a proven track record for on-time delivery are also important considerations. Velosity combines engineering, tooling, molding, and quality expertise under one roof to help reduce lead times and deliver consistent results throughout the product lifecycle.
How Do I Choose the Right Material for Injection Molding?
The right injection molding material depends on your part’s mechanical properties, operating environment, regulatory requirements, manufacturability, and cost objectives. Factors such as strength, flexibility, chemical resistance, temperature performance, and biocompatibility may all influence material selection. Velosity’s engineering team works with customers early in the design process to recommend materials, including thermoplastics, TPEs, LSR, and specialty resins, that meet performance requirements while supporting efficient manufacturing.
What Industries Use Injection Molding Contract Manufacturers?
Medical device, defense and aerospace, automotive, electronics, industrial equipment, and consumer product manufacturers all use injection molding to produce precise, repeatable plastic components at scale. The right manufacturing partner should have the quality systems, engineering expertise, and production capacity to meet each industry’s regulatory and performance requirements. Velosity has extensive experience supporting medical and defense programs, where contamination control, traceability, and on-time delivery are critical.
What Should I Look for in a Micro Molding Company?
Look for a micro molding company with expertise in precision tooling, tight-tolerance manufacturing, material selection, and quality inspection for small, complex components. Experience serving regulated industries, engineering support, and the ability to scale from prototyping to production are also important considerations. Velosity combines these capabilities with advanced micro molding expertise to help customers manufacture highly precise components for medical, defense, and industrial applications.
