How much does it cost to injection mold plastic?
Injection molding costs vary based on part complexity, size, material selection, and production volume. Tooling costs typically range from a few thousand to tens of thousands of dollars depending on mold complexity. Per-part pricing can be as low as pennies for high-volume runs. At Evok, we're transparent about costs from the start, providing detailed pricing breakdowns so you can make informed decisions. We offer engineering services at $110/hour and prototypes from $100-$300 depending on size. Contact us for a customized quote based on your specific project requirements.
Is injection molding cheaper than 3D printing?
For low-volume production (typically under 100-500 parts), 3D printing is usually more cost-effective as it requires no tooling investment. However, injection molding becomes significantly cheaper for medium to high-volume production due to low per-part costs once tooling is complete. Injection molding also offers superior material properties, finish quality, and production speed for volume manufacturing. We offer both rapid prototyping and injection molding services, helping you choose the right approach based on your volume needs, timeline, and budget.
What is the typical lead time for custom injection molded parts?
Lead times depend on project complexity and our current production schedule. Rapid prototypes typically take 1-3 weeks, while production tooling can take 4-8 weeks from design approval. Once tooling is complete, production runs can be scheduled based on your volume requirements. Our streamlined new part development pipeline is designed to accelerate speed to market. We'll provide a detailed timeline during your initial consultation based on your specific project parameters.
What materials can you work with for injection molding?
We work with a comprehensive range of thermoplastic materials including ABS, polycarbonate, nylon, polypropylene, polyethylene, acetal, TPE, and engineering-grade resins. Our material selection service helps you navigate material and texture science to choose the optimal resin for your application's functional, aesthetic, durability, and cost requirements. We consider factors like strength, flexibility, chemical resistance, temperature tolerance, and finish requirements to recommend the best material for your specific use case.
Do you provide design assistance for injection molding optimization?
Yes, comprehensive design assistance is a core part of our service. Our CAD design services review and modify your files for mold-ready design for manufacturing execution. We implement changes for moldability, optimize wall thickness, adjust gate and vent sizing, and minimize defects like sink marks and flash. Our team uses SOLIDWORKS and provides detailed redlining to document how design changes improve part manufacturability and reduce costs. We can start with your existing 3D files or model from scratch.
What quality control measures do you have in place?
We implement rigorous quality control throughout the entire process. Our parts qualification services include detailed molding trial reports monitoring mold fill speed, knit line locations, zone temperatures, and cycle time. First article qualification involves 30 inspection points per cavity for critical dimensions and 5 inspection points for non-critical dimensions. We provide comprehensive data to understand process variation and ensure parts meet your specifications. Our team includes a Six Sigma black belt and we use analytical testing tools to solve problems proactively.
Can you handle both prototype and production volumes?
Absolutely. We offer a complete new part development pipeline from concept feasibility through high-volume production. Our services include rapid prototyping for design validation, single-cavity tooling for beta development and testing, and optimized production tooling for volume manufacturing. This comprehensive approach allows us to support your project at every stage, ensuring smooth transitions from prototype to production while maintaining consistency in quality and specifications throughout the development lifecycle.
What industries do you serve with injection molding services?
We serve diverse industries including powersports, medical devices, semiconductor equipment, consumer products, packaging, and more. Our team has extensive experience working with OEMs across multiple sectors, from ultra-clean liquid delivery systems for high-purity chemical applications to consumer products for major brands like Rollerblade, Polaris, General Mills, and Boston Scientific. Our 25 years of cross-industry experience means we bring best practices and innovative solutions from multiple sectors to every project we undertake.
