The technology research and development team of Dexin Precision consists of 7 members. Despite its small size, it covers three key areas: mechanical design, numerical control system development, and material application. Each member has over 8 years of experience in the spring machine industry. The team leader is a senior engineer who has been deeply engaged in mechanical design for 12 years. He has led the structural optimization of multiple domestic numerical control spring machines, and has a profound understanding of the mechanical accuracy control of wire feeding and winding mechanisms. The numerical control system development specialist has participated in the early writing of spring machine numerical control programs, is proficient in the coordination logic of servo motors and PLCs, and can quickly adapt to the control requirements of different working conditions. The materials engineer focuses on the material selection and performance optimization of key components of spring machines (such as wire feeding rollers and winding spindles), ensuring the stable operation of the equipment in the hot and humid environment of Dongguan. All members have a bachelor's degree or above in mechanical engineering, and 2 members hold the "Guangdong Provincial Special Certification for Numerical Control Equipment Research and Development", making up for the shortage of numbers with professional depth.
Focusing on the needs of the spring industry in Dongguan and its surrounding areas (electronics, hardware, auto parts, etc.), the team has carried out "micro - innovation + strong adaptation" research and development. For the production of micro - springs (wire diameter 0.15 - 1.0MM) in the electronics industry, the ultra - small numerical control system has been optimized. The volume of the operation panel has been reduced by 30%, and at the same time, the human - machine interaction has been strengthened, enabling the winding accuracy of 0.01MM wire diameter springs to reach ±0.01MM. To solve the multi - axis linkage problem for hardware spring factories, by simplifying the transmission structure, the linkage error of two - to twelve - axis compression spring machines has been controlled within ±0.03MM, supporting the one - time forming of complex special - shaped springs. With low - cost intelligent transformation, a data acquisition module has been installed on traditional spring machines to achieve remote monitoring of the production status. This solution has obtained 2 utility model patents, helping small and medium - sized local customers in Dongguan to upgrade digitally.
Due to the limited size of the team, the research and development team cleverly uses the "external collaborative network": cooperating with the local mechanical research institute in Dongguan to carry out "spring machine structure fatigue testing", sharing test equipment and data; collaborating with the automation major of universities, introducing postgraduate students to participate in the optimization of intelligent control algorithms, reducing the research and development cost by 40%. At the same time, a "rapid customer demand response mechanism" has been established: when a customer puts forward a special process requirement (such as the end - forming of automotive seat springs), a preliminary plan is provided within 24 hours, and the prototype debugging is completed within 3 days, quickly adapting to the "small - batch, multi - variety" production rhythm of Dongguan's manufacturing industry, enabling a small research and development team to accurately reach the pain points of the market.
The production and manufacturing team consists of 8 people, including three types of roles: machining, assembly and debugging, and quality inspection, constructing a streamlined structure of "2 (machining) + 4 (assembly) + 2 (inspection)". The machining personnel are senior fitters and turners with more than 10 years of experience. They are proficient in operating small and medium - sized numerical control machining centers in Dongguan, controlling the machining accuracy of key components such as wire feeding rollers and winding spindles to ±0.02MM. The assembly and debugging personnel adopt the "mentorship system", with 1 senior assembly technician leading 3 apprentices, strictly following the "Dongguan Area Spring Machine Assembly Process Manual" to ensure the multi - axis linkage accuracy of two - to twelve - axis equipment. The quality inspection personnel hold the "Dongguan Metrology and Testing Qualification", using coordinate measuring machines and laser interferometers to conduct full - process inspections of the equipment. Before leaving the factory, they simulate the typical working conditions of Dongguan customers (such as continuous 12 - hour production) to intercept potential fault hazards.
In response to the "cost - reduction and efficiency - improvement" needs of Dongguan's manufacturing industry, the production team has optimized the "standardization + customization" production: 70% of the structural parts of the compression spring machine are pre - fabricated in a standardized manner, shortening the customization cycle to 5 - 7 days; key components (such as Taiwan - made system controllers) are purchased locally, reducing logistics and time costs. Through lean production management, the workshop inventory has been compressed, and the work - in - process turnover rate has been increased by 30%, enabling small - batch orders to be profitable. At the same time, inheriting the "craftsmanship of Dongguan manufacturing", each piece of equipment undergoes "manual accuracy verification": after assembly, the technician uses a dial indicator to detect the parallelism and coaxiality of the wire feeding and winding mechanisms point by point, ensuring that the equipment can operate continuously for 300 hours without failure in the high - temperature and high - humidity environment of Dongguan.
A "Dongguan - characteristic quality feedback chain" has been established: because customers are concentrated in Dongguan and its surrounding areas, after - sales engineers can arrive at the site within 2 hours. The quality problems collected (such as the aging of electrical components in a hot and humid environment) are feedback to the production team within 48 hours, and targeted protective measures are optimized (such as adding a moisture - proof coating). The common faults of local customers in Dongguan (such as the wear of wire feeding rollers) are included in the "preventive maintenance list", and customers are trained synchronously when the equipment is delivered, reducing the incidence of similar faults by 30%. With the efficient collaboration of a small team, the quality reputation is firmly established.
The marketing team consists of 4 people, focusing on the spring industry in Dongguan and the Pearl River Delta, with a clear division of labor: Industry researchers deeply explore the local market, visiting more than 10 customers every month, and sorting out the demand trends of spring machines in the electronics and hardware industries (such as the demand for intelligent micro - spring machines in electronics factories); Solution designers understand technology and the market. According to the research results, they can provide a "equipment configuration + process adaptation" solution for customers within 1 hour. They once quickly matched a 0.2MM wire diameter spring machine for an electronic parts factory in Dongguan, helping it to start production within 3 days; Sales specialists are familiar with the distribution of Dongguan's industrial belts and are good at exploring customers in subdivided fields such as hardware and auto parts. Through "word - of - mouth referrals from old customers", the business covers 80% of the spring industry gathering places in Dongguan, with more than 20 new customers added annually.
The after - sales team consists of 2 people (including part - time technical support), implementing the "Dongguan local fast - repair service": they are stationed in Dongguan, equipped with a mobile spare parts library (including common wire feeding rollers and servo motor encoders) and repair tools (high - precision straightening instruments). After receiving a customer's repair request, they respond within 1 hour and arrive at the site within 3 hours (in the urban area of Dongguan). General faults can be repaired within 4 hours, and complex faults can be solved within 24 hours. At the same time, "preventive after - sales" is carried out: every quarter, they visit customers to "examine" their equipment, clean the dust in the electrical cabinets in the hot and humid environment of Dongguan, check the wear of transmission parts, and replace potentially faulty parts in advance, reducing the equipment downtime rate by 40%. With remote assistance, they guide customers to solve simple debugging problems (such as parameter resetting), enabling the service to cover Dongguan and its surrounding towns and streets, adapting to the efficient rhythm of the local manufacturing industry with a "small team, fast response".
The marketing and after - sales departments collaborate to create a "Dongguan - characteristic service package": providing "3 - day on - site training" for new customers, teaching operation and maintenance knowledge, covering more than 90% of local customers in Dongguan; launching a "trade - in + upgrade and transformation" program for old customers, offsetting 10% of the purchase price of new equipment with old equipment, and at the same time providing low - cost intelligent transformation (such as installing a data dashboard) to help customers reduce costs and upgrade. Through "small - team full - process service", customers can seamlessly transition from "buying equipment" to "using it well". With a 4 - person team, a 95% customer satisfaction rate in Dongguan and its surrounding markets has been achieved. By leveraging a small team, they have firmly established themselves in the local spring machine market.
With a team configuration of "small but specialized, precise but strong", Dexin Precision deeply adapts to the manufacturing ecosystem of Dongguan: research and development focuses on local - scenario micro - innovation, production upholds the craftsmanship of Dongguan manufacturing, and marketing and after - sales are rooted in the local area with rapid response. With a scale of 10 - 20 people, it constructs a closed - loop of "research and development - production - marketing - after - sales", demonstrating that a small team can also create great value in a niche field, becoming an "invisible deep - plower" in the Dongguan spring machine manufacturing track.
