Office Phone Back Cover Injection Mold - Precision Customization & Global Delivery Solution

As a core mold for office electronic accessories, the office phone back cover injection mold balances structural stability, molding precision, and mass production adaptability. Specifically engineered for the mass manufacturing of back covers for various business phones and office communication devices, it meets the dual requirements for quality and efficiency in the global market.

Core Material & Process Advantages

The mold body adopts a combination of P20 pre-hardened steel and NAK80 mirror steel. The cavity undergoes CNC precision machining and mirror polishing, achieving a surface roughness of Ra≤0.8μm, which ensures the back cover products are free from shrinkage marks and flash—aligning with the minimalist aesthetic demands of office equipment. All steels have passed RoHS and REACH environmental certifications with traceable material compositions, compatible with mainstream injection molding materials such as PP and ABS. Boasting a load-bearing capacity of over 300kg, the mold can operate continuously for 500,000 shots without deformation. To address the shock-resistant and wear-resistant needs of office phones, the cooling channel design is optimized, with the temperature difference controlled within ±5℃, significantly improving product molding consistency.

Flexible Delivery & Standardized Processes

• Regular Orders: 4-6 weeks for single-cavity molds; 6-8 weeks for double-cavity/multi-cavity molds (covering design, trial molding, and optimization).

• Rush Order Service: Priority scheduling for core processes enables single-cavity mold delivery within 3-4 weeks, catering to customers’ urgent production needs.

• Transparent Processes: A DFM (Design for Manufacturing) analysis report will be provided within 3 working days after contract signing. Three free adjustments are offered during the trial molding phase to ensure dimensional tolerance is controlled within ±0.03mm. Supports STEP and X_T format drawing docking; production commences only after customer confirmation of the design plan to avoid rework delays.

Global After-Sales Service Guarantee

• Quality Warranty: 1-year free warranty (or 500,000-shot warranty). Free repair and spare parts replacement are provided for non-human-induced damage during the warranty period.

• Technical Support: A complete technical document package (including 2D/3D drawings, BOM lists, and molding process parameters) is delivered alongside the mold. 24/7 remote technical guidance is available to assist customers in rapid commissioning and production.

• Value-Added Services: Each mold is accompanied by a free wear part kit (including ejector pins, springs, sealing rings, etc.). The maintenance response time is ≤48 hours, and overseas customers can enjoy expedited delivery of spare parts from nearby warehouses.

• Lifetime Maintenance: Cost-effective repair and mold refurbishment services are offered after the warranty expires, helping customers extend the mold’s service life.

Adaptability & Customization Advantages

Compatible with the size specifications of mainstream office phone brands, it supports single-cavity and double-cavity customization for products weighing 10-50g. Adopting a standardized mold base design, it is compatible with parameters of mainstream injection molding machines worldwide. Customized development is available based on customer-provided samples or STEP/X_T format drawings. All molds are packaged in shockproof wooden boxes with moisture-proof and rust-proof treatment, ensuring safe cross-border transportation. Certified by EU CE and US FDA, the molds can seamlessly integrate into the European and American office electronics supply chains.

Translation Highlights

1. Technical Accuracy: Professional terms (e.g., "pre-hardened steel", "mirror polishing", "DFM analysis") and technical parameters (e.g., "Ra≤0.8μm", "500,000 shots") are translated in line with international industry standards for clarity and credibility.

2. SEO Optimization: Naturally embeds high-traffic keywords such as "office phone back cover injection mold", "precision customization mold", and "RoHS compliant injection mold" to enhance global search visibility.

3. International Adaptability: Adjusts expressions to fit global business conventions (e.g., "24/7 remote technical guidance", "500,000-shot warranty") and retains recognized certification abbreviations (RoHS, REACH, CE, FDA) for easy understanding across markets.

4. Consistency & Fluency: Maintains consistent terminology throughout and uses concise, marketing-friendly language to highlight product strengths, catering to overseas buyers’ reading habits.
