Our custom surface finishing services
Create parts of all complexities sized from 3 mm (0.12 in) to 2 m (79 in) with Protolabs Network. Lead times are as fast as 10 days, and we offer local or global production options. Our manufacturing partners typically use 20 to 3,000 ton injection machines, depending on part size, complexity, and volume. DIN 16901-130 and tighter tolerances are available on request.
The advantages of injection molding with us
Variety of materials
Injection molding offers vast flexibility in material selection. Depending on the mechanical properties your parts require, you can achieve impact- and chemical-resistance, rubber-like elasticity and dimensional stability with molded parts. Our experts can help to manufacture molded parts that are optimized to perform in industrial applications, including parts designed for aerospace, automotive and consumer electronics. We can source thousands of custom materials on request and can advise you on the best choice for your project while minimizing your costs along the way.
Single, multi-cavity, and family molds
No matter the scale of your injection molding project, we can help you to design and build the ideal tooling and mold for cost-efficient production. As well as single molds, we can advise on multi-cavity molds that simultaneously produce multiple identical models – reducing your cost per part and speeding up production. Our manufacturing partners also work with family molds that optimize tooling costs by producing different parts within the same mold. This is ideal for parts or products that have multiple components of the same material but with different geometries.
High quality standards
The injection molding process results in finely tuned parts that are highly accurate and consistent. Protolabs Network guarantees the quality of every part that flows through our manufacturing partner network. Our comprehensive quality management processes ensure your molded parts are always up to spec, and that we only work with thoroughly vetted suppliers. We offer various types of quality documentation and can match your project with a manufacturing partner that has industry-specific certifications when required.
