Recently, a delegation of Vietnamese clients visited Guangdong Zhengfeng Wire&Cable Co., Ltd. General Manager Sunny accompanied the delegation throughout the visit, engaging in in-depth discussions on the entire wire and cable production process, market trends in the cable industry, future plans, and prospects for future cooperation.
Upon arrival at Guangdong Zhengfeng Wire&Cable Co., Ltd., the Vietnamese delegation first toured the company's production workshop. Accompanied by technical personnel, the delegation members observed the entire wire and cable production process up close.
The various equipment in the workshop was arranged according to the product requirements and process flow. This precise production line layout attracted particular attention from the Vietnamese clients.
During the copper stranding process, the technical personnel explained in detail that copper stranding is a crucial step in combining multiple single copper wires into a conductor according to specific rules. By spirally stranding the conductors with a specific twist pitch, the flexibility and stability of the cable are significantly improved. The standard stranding direction is "S-direction" (left-hand). Key parameters also include: single wire diameter, number of strands, stranding pitch ratio, and tightness, all of which collectively ensure the conductor's excellent electrical and mechanical properties. This is the first step in wire and cable production and directly affects the conductivity and quality stability of the final product.
The delegation also focused on the insulation extrusion process. The technical requirements for plastic insulation extrusion include eccentricity control, surface smoothness, and cross-sectional density. Zhengfeng Wire&Cable's workshop has silicone wire production lines, teflon wire production lines, and PVC wire production lines. The insulation extrusion process differs for each production line; for example, silicone wire insulation requires a rubber compounding process, while Teflon wire insulation requires baking and heating. Vietnamese customers frequently raised questions, which Zhengfeng's technical staff answered one by one, creating a positive and professional atmosphere.
The quality management aspect was particularly emphasized by the Vietnamese delegation. They observed that at Zhengfeng Wire, quality inspection is integrated throughout the entire production process. The inspection department conducts roving inspections of the entire production process, operators perform self-inspections, and upstream and downstream processes conduct mutual inspections. This multi-layered quality control system ensures high-quality product standards.
In the subsequent business meeting, both sides focused on discussing the current demand and future trends for wires and cables in the Vietnamese market. According to industry analysis, the Vietnamese wire and cable market is in a phase of rapid growth, primarily driven by rapid infrastructure expansion and accelerated industrialization. Zhengfeng Wire also shared its project experience with Vietnamese clients, reflecting on how it has maintained steady progress amidst rapid market changes and market conditions.
The company has established a strict quality control system, rigorously controlling quality throughout the entire process from raw material procurement, production, transportation, and sales.
Addressing the industry-wide risk of raw material price fluctuations, Zhengfeng Wire has adopted effective countermeasures. We discuss and collaborate with clients to mitigate the risks associated with copper price volatility.
In terms of technological innovation, Zhengfeng Wire keeps abreast of industry trends. Relevant personnel travel abroad for training and participate in industry technical seminars. Based on market trends and factory conditions, we continuously optimize our product structure and increase product added value.
