Our Services
Posted on 2020-01-01
As a one-stop precision metal component manufacturer for global industrial buyers, Zhongzhu Technology integrates all production links internally to deliver integrated, low-cost and stable manufacturing solutions. Our full service system covers mold development, die casting forming, multi-axis CNC machining, surface finishing, professional quality control, flexible order delivery and full technical after-sales support.
1. Custom Mold & Tooling Development Service
Our independent mold workshop completes the whole mold manufacturing process without outsourcing. Based on your CAD drawings, our engineers carry out 3D modeling and DFM manufacturability evaluation at the early stage to eliminate potential casting and machining defects in advance.
We produce aluminum/zinc/magnesium die casting molds and custom CNC fixtures with EDM, wire cut and 5-axis milling equipment. We provide full mold trial, dimension revision and long-term maintenance service; simple minor mold repairs are free during mass production to extend mold service life.
Lead time: 5–7 days for simple molds, 10–15 days for complex thin-wall & RF cavity molds with sample delivery.
2. High-Pressure Alloy Die Casting Service
We provide aluminum, zinc and magnesium alloy die casting production to meet lightweight, complex housing manufacturing demands. Our mainstream products include 5G RF antenna housings, new energy auto structural parts, security camera enclosures and electronic heat sinks.
Our mature thin-wall casting process effectively reduces internal pores, cold shut and deformation, while maintaining stable air tightness for communication components. We accept both small-batch prototype trial orders and mass bulk production up to hundreds of thousands of pieces.
3. 4 & 5 Axis CNC Precision Machining Service
Equipped with 3/4/5-axis milling and turn-mill composite machines, we offer secondary precision processing for extruded aluminum profiles, die cast blanks and solid metal stock including aluminum and stainless steel.
We strictly control micron-level dimensional tolerances for slots, threads and assembly positioning surfaces. All critical workpieces are fully measured by CMM coordinate measuring machines to satisfy strict technical standards of telecommunication, medical and automotive industries.
4. Integrated Surface Finishing Service
All surface treatment processes are finished in our own factory to unify quality control and shorten lead time, without third-party outsourcing risks.
Available processes:
Type I conductive anodizing, Type II decorative anodizing, Type III hard coat anodizing with customizable colors
Electroplating, powder coating, chemical passivation, polishing, vibration deburring and conductive coating
We test coating thickness and salt spray corrosion resistance for every batch of finished products and record complete test data for customer reference.
5. Full-Range Traceable Quality Control Service
Sticking to our core principle “We Ensure Quality in Every Step”, we implement 7-layer quality inspection throughout all production steps:
Raw material spectral composition inspection and RoHS/REACH material certification verification
First-piece confirmation for each production shift, sampling inspection every 2 hours during mass production
CMM full dimension scanning for finished precision components
Special air tightness testing for 5G RF antenna cavities
100% visual appearance sorting to reject scratched, deformed and discolored parts
Final outgoing inspection following international AQL standards
Complete COA inspection reports and batch traceability records provided for every shipment. We support third-party SGS inspection as required.
6. Flexible Sampling & Global Export Delivery Service
Fast prototype sampling: Samples delivered within 3–7 days after drawing confirmation, with free DFM optimization feedback to cut your mold & production cost
Flexible MOQ: No high minimum order quantity restriction, supporting small R&D trial batches and long-term large-volume export orders
Custom anti-rust export packaging: Vacuum anti-rust bags, foam separators and moisture-proof cartons to prevent scratch and corrosion during long sea transportation
Stable on-time delivery: Over 97% on-time rate for mass orders, with real-time production progress updates sent to clients regularly.
7. Multilingual Technical & After-Sales Support
Our multilingual engineering & sales team replies to RFQ inquiries within 24 hours, providing free professional suggestions on material selection, processing technology and cost balance.
We supply complete ISO9001 and IATF16949 quality system documents, as well as RoHS & REACH compliance certification for EU market export. For any quality feedback, we respond within 8 working hours and deliver full root cause analysis & improvement plans within 24 hours to avoid repeated defects in subsequent batches.
