Find answers about tooling ownership, production capabilities, materials, lead times, and our injection molding process.
While aluminum tooling degrades rapidly under high thermal stress, low volume steel tooling ensures uncompromised structural integrity without tool wear for a 1,000-piece run. Hardened P20 steel molds deliver true production-grade quality, effortlessly processing harsh engineering resins like glass-filled nylon. This makes the low volume injection molding process the superior choice for rigorous engineering validation and bridge production, avoiding the fragility and dimensional instability of aluminum prototypes.
The physical requirements for draft angles remain identical to mass production, typically requiring a minimum of 1 to 2 degrees per side for standard finishes. Because low volume plastic molding utilizes hardened steel, specific VDI/SPI surface textures can be achieved, which often require increased draft angles. A thorough DFM analysis verifies the CAD geometry to ensure proper draft is applied, preventing ejection issues on custom short run injection molding components.
Because precision CNC-machined steel molds are utilized, low volume injection molding standard tolerances align perfectly with mass-production capabilities. Typically, standard machining tolerances remain at ±0.05mm, with ultra-tight tolerances reaching ±0.02mm for critical geometric features. This precision ensures injection molding small parts achieve perfect snap-fit assembly. These strict dimensional requirements are continuously verified using advanced CMM equipment throughout the entire small batch plastic manufacturing cycle.
Absolutely. Specialized injection molding solutions for small batch runs easily accommodate complex geometries, including deep undercuts, living hinges, and internal threads. To keep upfront tooling costs manageable during low-volume production, hand-loaded core inserts or simplified slider mechanisms are frequently utilized instead of expensive automated lifters. During the initial DFM phase of a low volume injection molding project, these complex features are strictly optimized to balance functionality with cost-efficiency.
We process premium engineering plastics including ABS, PC, PP, PA, etc. equipped with injection molding machines ranging from 100 to 800 tons.
