Texin — Reliable Container Injection Molds for Durable, Precise Containers

Texin designs and manufactures high-quality container injection molds for a wide range of plastic containers — food jars, storage tubs, cosmetic jars, medical vials, canisters and industrial drums. Containers require more than shape: they demand uniform wall thickness, tight dimensional control for lids/fits, consistent surface finish, chemical resistance and long tool life for high-volume runs. Our container injection molds combine careful DFM, correct steel selection and precision machining so your parts come out right every cycle.

Why container injection molds are special

• Wall uniformity and warpage control: Containers often have thin walls and tall sections; design-for-injection prevents sink and warp.
• Fit and sealing: Lids, threads and snap-fits need repeatable tolerances to ensure sealing and assembly.
• Surface and appearance: Food or cosmetic containers may need smooth or textured finishes; decorative surfaces require mirror-grade steel and polishing.
• Production life: Many containers are high-volume — molds must run thousands to millions of cycles while keeping dimensions and finish stable.

What Texin provides

• End-to-end service: feasibility review → mold design → materials procurement → precision CNC/EDM machining → assembly & debug → trial molding & optimization.
• Fast feasibility and design: initial feasibility checks take 1–3 days; standard mold design 3–7 days (complex designs longer).
• Correct material choices: 45# for low-volume, 718H for mid-volume, S136 (mirror grade) for high-polish/chemical resistance, NAK80 when minimal heat treatment is preferred. Domestic steel is usually available in 1–3 days; imported mirror steels may take 1–4 weeks.
• Realistic cost & schedule view: material typically accounts for ~20–30% of mold cost; machining and processing drive ~30–50% of cost and 40–60% of lead time. Expect machining/parts work to be the largest time component.
• Precision machining: CNC provides micron-level accuracy; EDM/WEDM and polishing deliver required finishes for container faces, threads and sealing surfaces.
• Trial runs: we include at least one official trial (installation, test shots, initial adjustments). Trial runs typically take 1–3 days; 2–3 iterative trials are common for complex molds.

Buyer & producer questions (concise, data-backed)

Q: What files do you need to start? A: Send a 3D model (STEP/IGES/Parasolid) plus a 2D drawing with key dimensions, target material, surface finish and expected annual volume. That enables a 1–3 day feasibility review.

Q: What deliverables are included in design? A: Typical package: mold assembly drawings, cavity/core layout, runner/gate plan, cooling layout and BOM. Moldflow simulation available as optional service.

Q: Which steels do you recommend for containers? A: 45# for prototypes/low volume; 718H for medium runs; S136 for mirror finishes or corrosive use; NAK80 when avoiding heavy heat treatment. Choose by required finish, cycle life and budget.

Q: How long from drawing to first trial? A: Feasibility 1–3 days; design 3–7 days; machining & assembly commonly 2–4 weeks for medium complexity (machining/processing often 40–60% of lead time); trial/validation 1–3 days per run.

Q: What about surface finish options? A: CNC gives base geometry. Mirror finishes require polishing and fine EDM; textured finishes are laser-engraved or chemically etched. For high-gloss containers, use S136 + polishing.

Q: What inspection & tolerance control do you apply? A: Multi-stage inspection with CMM checks, visual inspection and sample validation during trials. We support customer AQL/inspection plans on request.

Q: What is included in trial runs and cost expectations? A: One official trial is included (installation, test shots, initial adjustments). Each trial usually takes 1–3 days. Single trial costs can range from several thousand depending on machine time and adjustments.

Q: Warranty & after-sales? A: We offer an agreed warranty period (typical commercial practice: one year or an agreed number of shots). Spare parts (ejector pins, sleeves) and maintenance services are available.

Quick summary 

Container injection molds need careful DFM, correct steel selection (45#, 718H, S136, NAK80), and precision CNC/EDM finishing to ensure uniform walls, sealing fits and consistent finishes over long runs. Texin’s six-stage workflow (feasibility → design → material → machining → assembly → trial) delivers predictable schedules and quality. Material usually represents 20–30% of mold cost; machining and processing are the biggest time and cost drivers (40–60% lead time, 30–50% cost).

If you’re sourcing container injection molds, send Texin your 3D files, 2D key dims, target material and expected volume. We’ll return a feasibility review, timeline and tailored plan to get your container parts into reliable production.
