So many customers trustRaytron（RaytronThe fundamental reason for the small-size copper wire of Ruichuang is that it not only has solid technical strength and reliable product quality, but also has strong delivery capabilities, professional services and high cost performance. The following is an analysis of the core trust reasons why customers widely choose Ruichuang:
? 1. Excellent technology, can really make small-sized copper wire
Strong ability to produce extremely small specifications: Ruichuang can mass-produce ultra-fine copper wires with a diameter of 0.05mm and above, and has rolling and drawing technology with a width-to-thickness ratio of ＞100;
Advanced equipment support: We have independently designed high-precision rolling mills and wire drawing equipment, and adopt a constant tension control system to ensure that the fine wire is not broken or stuck;
High-end raw material matching: Use high-quality copper materials such as oxygen-free copper and T2 copper to ensure that the conductivity, ductility and corrosion resistance all meet high-quality standards.
? 2. First-class surface quality and high conductivity stability
Deoxidation + multi-stage cleaning + passivation and anti-oxidation: completely solve the problem of thin copper wire being easily oily, oxidized and rusted;
AI visual inspection system: fully automatic identification of surface defects such as broken wires, scratches, white spots, black stripes, and discoloration;
The whole roll has excellent continuity: no burrs, no clamps, consistent wire diameter, suitable for automatic welding, winding and sleeve threading.
? 3. High dimensional accuracy and strong performance consistency
The control error is within ±0.005mm, or even stricter;
It can meet the various requirements of different customers on resistance, conductivity, elongation, etc.;
High batch consistency, suitable for high-end scenarios such as precision electronics, BMS, wiring harnesses, FPC, etc.
? 4. Flexible customization and fast delivery
Flexible specifications: within the range of 0.05mm~0.5mm, any wire diameter and state (soft, semi-hard, hard) can be customized;
Small minimum order quantity, support proofing verification;
Samples can be delivered as quickly as 48 hours, and regular mass production specifications can be shipped quickly, which is suitable for new product development and batch delivery.
? 5. Strict quality control system and stable batches
Strictly implement ISO quality management system;
The whole process testing includes: wire diameter, resistivity, tensile strength, bending resistance, surface condition, weldability, etc.
With multiple QC steps, the qualified rate of finished products is high and the rework rate is extremely low.
? 6. Professional service and efficient communication
A dedicated team of technical engineers is set up to provide customers with technical support for the entire process including copper wire selection, processing, welding, etc.
Provide complete information such as test reports, COC, material certification, RoHS, REACH, etc.;
We have a fast communication response and help customers solve technical problems, which is well-known.
? 7. Strong industry influence and broad customer base
National high-tech enterprises and standard setting units;
Multiple patented technologies (such as small-size copper wire forming, anti-oxidation treatment process, etc.);
It is widely used in photovoltaics, new energy, smart terminals, batteries, automotive electronics, home appliance connectors and other fields;
Many of the world's top 500 supporting factories are using Ruichuang copper wire.
?? To sum up in one sentence:
Ruichuang is not a "cheap choice", but it is definitely the "right choice". It has won the trust of more and more high-standard customers with real technology, reliable quality and professional services.
