What is low volume injection molding?
Low volume injection molding is a manufacturing process that produces plastic parts in smaller quantities (typically 100-10,000 units) using cost-optimized tooling such as aluminum molds or soft steel tooling. It bridges the gap between prototyping and full production, allowing companies to manufacture production-quality parts without the significant investment required for high-volume production molds. This approach is ideal for market testing, crowdfunding fulfillment, beta launches, and validating product-market fit before scaling to mass production.
What is the minimum quantity for injection molding?
At Evok, our minimum quantity for low volume injection molding typically starts at 100 parts, though this can vary depending on part complexity, size, and material requirements. We work with startups to determine the optimal batch size that balances tooling costs, unit pricing, and your specific business needs—whether that's fulfilling initial orders, conducting market tests, or meeting crowdfunding commitments.
How much does low volume injection molding cost?
Low volume injection molding costs vary based on part complexity, material selection, tooling requirements, and quantity. Aluminum tooling for low volume production typically ranges from $2,000-$15,000 (compared to $25,000-$100,000+ for production steel molds), with per-part costs ranging from $0.50 to $10+ depending on size and complexity. We provide transparent, upfront pricing and work with you to optimize design features that reduce both tooling and per-part costs.
Is injection molding good for batch production?
Yes, injection molding is excellent for batch production, especially when using low volume tooling strategies. It delivers consistent, production-quality parts with repeatable dimensions and material properties—critical advantages over 3D printing or machining for quantities above 100 units. Low volume injection molding allows you to use the same materials and processes as full production, ensuring your batch parts accurately represent how your product will perform at scale.
What is an example of low volume production?
Common examples include crowdfunding campaign fulfillment (500-2,000 units), beta testing programs (100-500 units), market validation runs (1,000-5,000 units), seasonal product launches, trade show samples, and initial inventory for e-commerce launches. Startups often use low volume production to enter the market quickly, gather customer feedback, and refine their product before investing in high-volume production tooling.
Can LDPE be injection moulded?
Yes, Low-Density Polyethylene (LDPE) can be injection molded and is commonly used for flexible products, squeeze bottles, container lids, and applications requiring chemical resistance. LDPE offers good impact strength, flexibility, and moisture resistance at economical pricing. Our material selection experts can help determine if LDPE or alternative resins like HDPE, PP, or flexible TPE best suit your specific application requirements and performance goals.
How long does it take to produce low volume injection molded parts?
Timeline depends on design complexity and tooling requirements, but typically ranges from 4-8 weeks from final design approval to parts in hand. This includes 2-4 weeks for aluminum tool fabrication, 1 week for sampling and adjustments, and 1-2 weeks for production and shipping. Our streamlined process and cross-functional team focus on minimizing lead times to help you reach market faster.
What's the difference between prototype tooling and low volume production tooling?
Prototype tooling (rapid tooling) is designed for quick iterations and design validation, typically producing 10-50 parts with simplified construction. Low volume production tooling uses more durable materials like aluminum or P20 steel, includes production-grade features like multi-cavity capability and optimized cooling, and is built to produce hundreds to thousands of parts with consistent quality. Low volume tooling bridges to full production, often allowing tool transfer or scaling later.
