Customer Concerns
Precision – Misalignment of housing assembly clips? Inadequate sealing ring compression?
The meter housing involves multiple precision structures, including the fit between the upper and lower covers, clip positioning, terminal mounting holes, lead seal holes, and the pressing of the transparent window. Any dimensional deviation can lead to assembly failure or failure to pass IP protection testing.
Our Approach: Finite element topology optimization is performed using UG/NX during the mold structure design phase to ensure uniform distribution of cooling water channels and reduce thermal deformation.
The injection molding process uses Moldflow mold flow analysis to predict material shrinkage, filler end, and weld line positions, correcting defects during the design phase.
Key molding parts (core, cavity, slider, ejector pin) are all precision machined using 5-axis CNC machining combined with EDM (Electrical Discharge Machining) to ensure dimensional consistency.
Lifespan – Wearing out after tens of thousands of cycles? Frequent downtime for mold repair?
Mold lifespan directly impacts the cost per unit housing. If a high-precision mold can only be used for 100,000 cycles, the amortized cost per housing is five times that of a mold used for 500,000 cycles, and each mold repair causes production line downtime losses.
Our approach: We use imported high-strength pre-hardened steels such as S136H, 718H, and 2738 for our molds, with a hardness of HRC33-36, ensuring dimensional stability under high temperature and pressure.
All molded parts undergo deep cryogenic treatment (-190℃ × 6 hours) to eliminate residual austenite, improve microstructure uniformity, and increase wear resistance by over 50%.
The working surfaces of the moving mold, fixed mold, and slide block are treated with PVD vacuum ion plating or nano-coating, achieving a surface hardness of HV2000-3000, significantly improving anti-adhesive wear performance and increasing fatigue life by over 40%.
The hot runner system employs a precise temperature control module, maintaining the surface temperature difference of the cavity within ±2℃ to prevent localized overheating and premature steel failure.
Deliverables: Mold design life ≥ 500,000 cycles, maintenance cycle extended to 80,000-100,000 cycles, and rework rate reduced by over 30%.
Anti-Theft – Is the casing easily pried open? Are the lead seals easily damaged?
Anti-theft is one of the most pressing concerns for power companies worldwide. Whether the casing structure is tamper-proof directly impacts the meter manufacturer's bidding score.
Our approach: The mold structure integrates anti-pry latches and a push-in self-locking mechanism. After the casing closes, the latches reverse and lock, preventing external prying with screwdrivers or other tools.
The lead seal holes utilize a one-way anti-pull-out structure. Once the lead seal wire is inserted and pulled out, the seal body is destroyed and cannot be restored.
The casing screw fixing posts are designed as concealed countersunk holes, invisible and inaccessible from the outside.
The transparent window mold design, combined with a rationally structured ultrasonic welding line, ensures a secure weld between the transparent window and the base, preventing damage to the casing from unauthorized disassembly.
Results: Meets the power company's anti-theft technical specifications; the casing structure's anti-pry rating reaches industry-leading levels, effectively reducing disputes over line loss.
