Sinter
Sinter operates an autonomous injection molding factory that compresses the timeline from design to production parts. The company handles CAD intake, design for manufacturability, mold flow analysis, and tool design in-house, using polymer tooling to cut core and cavity production from weeks to days. Engineers upload designs and receive dimensionally in-spec parts without outsourcing molds.

Problem
Domestic injection molding is bottlenecked by the inability to produce molds effectively. Injection molding shops outsource, and lose money on, the production of molds in order to make back margin on a multi-year scale, leaving engineers waiting weeks to months for tooling and first articles.
Solution
Sinter operates an autonomous factory that accelerates the American plastics pipeline, compressing the timeline from design to production parts. The company handles injection molding in-house, including CAD intake, design for manufacturability, mold flow analysis, and tool design, with polymer tooling that cuts core and cavity production from weeks to days. Engineers can upload designs and receive dimensionally in-spec parts without outsourcing molds. The factory powers itself with real-time, intelligent decisions, allowing a radically faster iteration from design to prototype to production. Sinter's system lets customers revise, reconfigure, and deploy with zero downtime, staying planted in peak productivity regardless of design cycles.
Target Audience
Primary customers are engineers and product teams who need rapid iteration from design to prototype to production injection-molded parts without the traditional multi-week mold sourcing cycle.
Features
- Fully in-house autonomous factory covering CAD intake, DFM review, mold flow analysis, tool design, insert fabrication, and T1 sampling
- Polymer tooling that produces core and cavity from CAD to press in days, not weeks
- Automated DFM with draft, wall, and undercut review flags
- Mold flow simulation for fill, pack, and warp validation before the tool is cut
- Process window data (e.g., hold pressure adjustments) fed back to subsequent tooling runs
- Real-time intelligent decision-making across the production cycle for zero-downtime revisions
- Prototype quoting in minutes for FDM 3D-printed parts with price, lead time, and ship date provided online
