David Xia founded ZHENGWEI Electrical Machinery Co., Ltd. in Humen Town, Dongguan City, Guangdong Province, a famous wire and cable manufacturing zone in China.

ZHENGWEI changed its name to GEMWELL Electrical Machinery Co., Ltd. We have started the road of passionate innovation and development, and have rapidly become a in the field of electrical signal transmission wire & cable equipment manufacturer since then. As strategic partner of high frequency and high-speed communication cable manufacturers, GEMWELL cooperate with many famous customers in this field.

GEMWELL cooperated with Taiwan's largest wire connector enterprise to successfully launched the first "capstan type cantilever single twisting machine " in China which has been sold more than 200 sets every year, and has ranked No. 1 top sales product in this field for many years.

GEMWELL cooperated with Taiwan's famous high frequency cable enterprise to successfully developed "intelligent CNC vertical taping machine " in China which has been sold more than 200 sets every year. After decades research and development, GEMWELL tape wrapping machine has become a famous product in the industry, leading the sales for many years.

GEMWELL cooperated with China mainland largest wire connector enterprise to successfully developed " Micron wire Teflon extruder line " which has high concentricity and stable wire diameter, and has solved the production bottleneck of small size wire for high-speed transmission.

Cooperating with a well-known company in United States, GEMWELL designed and developed " QSFP high-speed transmission wire hysteresis tension taping machine", successfully entered the cloud computing high-speed transmission wire field.

Cooperated with a well-known company in Japan, GEMWELL designed and developed "center rotary type hysteresis tension back twisting pay off stranding line", leading cabling process of robotic cable, elevator chain cable etc. flexible cable.

GEMWELL has successfully developed "3000RPM constant tension copper wire bunching machine" and "alloy conductor back twist bunching machine" with stable pitch. After back twisting, there is no internal stress inside conductor. The production capacity is 5 times more than the tubular stranding machine and cage stranding machine.

Cooperated with well-known Taiwan data cable enterprise which factory in Dongguan city, GEMWELL developed "25+50+35 skin-foam-skin nitrogen injection physical foaming insulation extruder line" which has high concentricity, stable wire diameter and capacitance, and has solved the production bottleneck of small size data cable foaming insulation process.

The establishment of FELIX branch, positioning in the reliable pair twist equipment, developed " Integrated type triple twist pairing machine” in the same year, helping customers saving space occupation. With annual sales more than 200 units, the product became the No.1 seller in China.

Cooperated with one famous listed company in Zhejiang province, which is one of largest high speed transmission cable enterprise, GEMWELL developed "2000 RPM three servo power driven taping machine ". Since then, the manufacturing process of high-end wire and cable enters the " power driven era” in taping machine.

GEMWELL successfully developed the "three cores torsion free pair twist &taping machine". The signal core wires finish pair twisting and tape wrapping at one time to reduce the process flow and reach 100% back twist. The twisted products have no internal stress, which improves the cable structure stability.

GEMWELL successfully developed the "high efficiency extruder line". The extruding capacity is twice of same model extruder. For example, the output of 80mm extruder equals to the 120mm extruder, realizing the dual functions of one extruder, which can be used as both wire insulation and cable sheath extruding, saving customers’ equipment investment and space investment.

Cooperated with one famous high-speed transmission cable enterprise in Kunshan, GEMWELL developed "QSFP flat cable servo power driven constant tension fork stranding machine", successfully replacing the traditional planetary stranding process, keep constant tension on rotating cage, increased the original product qualification rate up to over 50%.

In order to meet customer needs and expand production scale, GEMWELL invested 100 million RMB to establish Jiangsu Technology Plant in Jiangsu Province, and build 28,000 square meters of intelligent industrial plants and R&D buildings to achieve large-scale and digital production.

Cooperated with one famous company in Zhejiang province, which is one of largest data cable enterprise, GEMWELL developed "All-in-one back twist pair twisting machine ". Occupy less space and produce cable in excellent performance, the new model pair twisting machine reached top sales in the world with annual sales over 200 units.

Cooperating with one of the world top three connector manufacturers from United States, GEMWELL designed and developed " 2500 RPM three servo power driven taping machine ". With high efficiency and stable quality, this machine has become the designated tape wrapping equipment for the global wire & cable enterprise.

Cooperating with Netherlands well-known flexible chain enterprise, GEMWELL designed and developed " Shaftless constant tension back twist stranding machine", created a new beginning of shaftless motorized back twist stranding.

GEMWELL successfully developed the "rotary capstan". Linkage with back twist pay off and large cantilever single twist machine, it has solved the problem of high-speed cabling for large cables diameter more than 30mm. The cabling speed is about 5 times to traditional cage strander.

Cooperating with a well-known German automotive wire harness enterprise, GEMWELL solved the problem of new energy vehicle network cable pair twisting process, successfully developed the "vehicle-mounted four cores/two cores data cable back twist pair twisting machine ", the stability and qualification ratio of the pair twisted products can exceed those of European and American machines, and low loss on flexible cable is leading technology in the world.
