Manufacturing · Injection Molding
From Prototype Parts to Production-Ready Components
SDI injection molding programs bridge industrial design and factory production — enclosure geometry, material selection, and tooling strategy engineered for repeatable, cost-effective molded parts.
Our Silicon Valley mechanical team coordinates DFM reviews, prototype tooling, and production mold release with electrical, firmware, and assembly disciplines so your product ships with molded components that fit the first time.
Designed for Manufacturing
DFM principles applied before tooling is cut — not after parts fail first article inspection.
Every molded enclosure passes design gates for wall thickness, draft angles, rib geometry, and gate placement so parts eject cleanly and assemble without force-fit rework.
SDI mechanical engineers work alongside industrial design and factory partners to validate material flow, shrink compensation, and tolerance stacks before steel is committed.

Request Free EstimateFrequently asked questions
Common questions about injection molding, DFM, tooling, materials, and production timelines.
What injection molding services does SDI provide?
Enclosure design, DFM, material selection, prototype tooling, production tooling, and manufacturing support.
What is DFM for injection molding?
Design for manufacturing — optimizing wall thickness, draft, ribs, gates, and geometry so parts mold reliably and assemble cleanly.
Do you support prototype tooling before production molds?
Yes. Soft tooling and bridge molds for EVT/DVT before committing to production steel.
Which materials do you work with?
ABS, PC, PP, nylon, TPE, and engineering resins selected for mechanical, aesthetic, and regulatory requirements.
Can you coordinate with PCB and assembly teams?
Yes. Internal clearance, connector access, and assembly interfaces are validated against molded geometry.
What product categories do you support?
Consumer electronics, robotics, IoT, medical, industrial, and smart building products among others.
How long does prototype tooling take?
Typical soft tooling runs 3–6 weeks depending on part complexity and finish requirements.
How long does production tooling take?
Production steel molds typically run 8–14 weeks including T1 sampling and process validation.
Do you handle texture and color matching?
Yes. Texture specs, color masterbatch, and cosmetic validation are part of tooling release.
