Full-Service Custom Injection Molding Capabilities
Everything your plastic component program needs — design, tooling, molding, decorating, assembly, and packaging — from a single Houston facility
Injection Molding Machines: Press capacity from 40 to 1,350 tons — small precision components and large structural parts, all under one roof.
Three Shifts, Five to Seven Days: Production capacity that scales to your demand — high-volume programs run around the clock when your schedule requires it.
Complete In-House Tooling: Mold maintenance, repairs, and insert changes handled by our own tool shop — design changes in days, not toolmaker lead times.
Advanced Mold Actions: Multiple core pull, hand-loaded cores, and automatic unscrewing cores — the complex geometries other molders quote away.
Secondary Operations: Plastic printing, part decoration, sonic welding, secondary machining, assembly, and custom packaging — your part arrives finished, not almost-finished.
Insert Molding & Overmolding: Plastic-over-metal and plastic-over-plastic molding for integrated, assembly-ready components.
People. Process. Technology.
Texas Injection Molding follows a simple strategy founded on People, Process, and Technology — bonded by a culture of respect and genuine concern for others. It is the secret sauce that makes us different, and it shows up in how every part is made.
Qualified Before Production: The manufacturing process for every part is optimized and qualified to repeatable standards before it is ever released to production.
Real-Time Process Monitoring: Every machine and key processing parameter is measured, reported, and recorded in real time — drift is caught as it happens, not at final inspection.
Barcode Lot Traceability: Materials are certified and lot tracked by barcode from receipt through finished part — a complete, audit-ready trail.
ISO 9001:2015 Certified: Manufacturing operations certified and audited — with machines and tooling calibrated and managed to established MRO standards.
World-Class Resin Partnerships
We partner with the world’s leading resin manufacturers and custom compounders, giving our customers deep technical resources in custom resin applications and testing.
When your part needs a material that does not exist on a distributor shelf — a specific chemical resistance, a certified food-contact grade, a custom compound — those relationships are the difference between “we cannot source that” and “here is the qualified material.”
Real-Time Visibility, Real Accountability
Our systems provide real-time access to inventory, scheduling, and machine utilization. When you ask where your order stands, the answer comes from live production data — not from a guess.
Combined with automation inside and outside the tool, sonic welding, printing, and custom packaging capability, the result is a manufacturing operation engineered to hit your dates and prove it.

Process Discipline You Can Audit
Qualified processes, real-time parameter monitoring, barcode lot traceability, and ISO 9001:2015 certification — proof, not promises.
Everything Under One Roof
Rapid prototypes and clinical builds produced in our own design centers — validation in days, iteration without vendor queues.
