Texin Pen Container Injection Product — Precision, Safety and Reliable Supply

At Texin we specialize in high-quality pen container injection products designed for education, stationery retail and promotional uses. A well-made pen container requires more than attractive styling — it must meet strict functional, safety and durability standards. Texin combines experienced mold-making (CNC, EDM and precision finishing) with optimized injection molding processes and material know‑how to deliver pen container injection products that satisfy both end users and manufacturers.

Why precision matters for a pen container injection product

• Function: hinges, latches and lids must open/close smoothly for everyday use.
• Safety: edges and corners must be free of burrs and sharp points for children’s products.
• Durability: repeated use, occasional drops and stacking require stable geometry and robust material selection.
  Texin’s production control focuses on those points: we design and manufacture molds precisely, control injection parameters, and carry out assembly and testing so each pen container injection product leaves our factory ready for market.

Key product highlights (what Texin provides)

• Materials: common choices are ABS and PP — ABS for rigidity and surface finish, PP (especially for living-hinge designs) for flexibility and fatigue resistance.
• Manufacturing: precision injection molding with tool steel molds made from appropriate grades (heat-treated steels for longevity), CNC-machined cores/cavities, EDM and polishing where required.
• Surface & decoration: options include texture (molded), spray/paint, silk-screen/pad print and decals to meet branding needs.
• Assembly: secure installation of zippers, magnets, snap-fit latches or other fittings; careful QC of moving parts.
• Quality standards built in: product-level tests and safety checks based on the requirements you expect from a pen container injection product.

Measured performance and safety targets (based on provided product requirements)

• Hinge durability: designed to meet an opening/closing life test of 500 cycles without fracture. This ensures basic daily reliability.
• Structural strength: withstands a 50 N pressure test without permanent deformation — this verifies basic crush resistance for stacked or packed items.
• Chemical safety: phthalates limit — total phthalates ≤ 0.1% (0.1% by weight) and compliance with migration limits such as GB 21027 where applicable.
• Edge safety: all exposed edges meet a minimum tip/fillet radius ≥ 0.5 mm and are free of burrs.

Common customer/producer questions (concise answers)

Q: What is the best material for a pen container injection product — ABS or PP?
A: Use ABS when you need good surface finish, color stability and moderate toughness; choose PP when you need flexibility (e.g., living hinges) and better fatigue life. Both are standard injection materials used by Texin.

Q: How do you ensure hinge durability?
A: We validate hinge design and process through life testing. Our acceptance target: 500 open/close cycles without fracture (per product requirement). Material selection and wall thickness at the hinge are optimized (PP often preferred for living hinges).

Q: What does the 50 N test mean?
A: It’s a simple structural check: apply 50 N at a defined spot and confirm the part does not show permanent deformation. It verifies everyday resistance to pressure for a pen container injection product.

Q: Are chemical safety limits enforced?
A: Yes. Texin follows the stated chemical safety target: total phthalates ≤ 0.1% and we can support third‑party testing (SGS/Intertek) and compliance documentation on request. We also check heavy‑metal migration against standards like GB 21027 when required by the buyer.

Q: How do you control sharp edges and ensure safety?
A: Mold design, gating and ejection are optimized so parts demold cleanly; we require exposed edges to have a curvature radius ≥ 0.5 mm and perform visual and sampling inspections to ensure no burrs remain.

Q: What surface finishing and decoration can you do on a pen container injection product?
A: Mold texture, painting, pad/silk printing, heat transfer and decals are commonly used. Each method has mold and process implications; we advise the best approach based on desired appearance and volumes.

Q: How precise are your molds and CNC processes?
A: Texin uses precision CNC and secondary processes (EDM, polishing) in mold manufacture so cavity geometry and surface finish meet design needs — essential for consistent pen container injection product quality and repeatable molding.

Q: Do you provide sample testing and third‑party reports?
A: Yes — samples and pilot runs are available. Third‑party testing (e.g., SGS/Intertek) can be arranged for chemical or mechanical tests on request.

Summary：

Why choose Texin for pen container injection products A pen container injection product must balance aesthetics, function and safety. Texin delivers that balance through precise mold-making, disciplined injection production, defined safety targets (500 hinge cycles, 50 N structural test, phthalates ≤ 0.1%, edge radius ≥ 0.5 mm) and practical finishing/assembly capabilities. Whether you’re specifying a classroom pen box or private‑label stationery, Texin is prepared to help with design-for-manufacture advice, sample validation and reliable volume supply.
