About InGen MillTek

YinJiang’s manufacturing business began in Jiangyin, Jiangsu Province in 1997, starting with machining and parts production. After moving to a new factory in 2001 the company began developing and building its own spiral accumulators, uncoilers and shear and butt welders, the entry equipment of tube mills; the YinJiang brand was established in 2004. Forming mills and flying saws followed in 2006, and a new production base and the first export sales in 2009. The company has also presented a technical paper on welded tube manufacturing at a national conference on roller tooling technology. In 2012 its YinJiang-brand spiral accumulators, tube forming equipment, uncoilers, shears and feeders were named Jiangsu Famous Brand Products. Slitting lines were integrated in 2013. JiangSu InGen MillTek Co., Ltd. was established in 2020 and recognized as a National High-Tech Enterprise in 2023. In 2025 the company’s English name was changed to InGen MillTek. Today JiangSu InGen MillTek Co., Ltd. (brand InGen MillTek) and its affiliated company Jiangyin Yinjiang Machinery Co., Ltd. serve the market together, with more than 60 employees and their own factory site of about 21,000 m².

Our products include complete high-frequency tube mill lines and slitting lines, and individual machines: uncoilers, levelers, shear and butt welders, spiral accumulators, forming and sizing mills and flying saws. Cold roll forming machines are custom-built per project — send us the profile drawing, material, thickness and output required. Our equipment is used by many tube makers in China and exported to the Middle East, Africa, Russia and Central Asia, South Asia, Southeast Asia, Europe and South America.

Besides complete lines under our own brand, we have also built complete tube mill lines for other manufacturers and trading companies, and we supply entry equipment such as uncoilers, shear and butt welders and spiral accumulators to tube mill builders and export traders in China. On projects marked “Via another mill builder”, the tube mill itself was not ours; each card lists only what we supplied.

Before a sale we design the line layout around the customer's products and workshop, advise on model selection and technical parameters, and sign a technical agreement that sets out delivery time, acceptance criteria and warranty. After delivery, our engineers guide installation and commissioning on site, with costs agreed per project; operator and maintenance training, spare parts and long-term maintenance are arranged within the agreed scope.

This website lists the models and equipment categories currently supplied. Specifications use the confirmed company product catalog and other referenced material, with their sources noted. Every line is configured for the customer's product and plant conditions, so pricing is discussed on the basis of the actual configuration. We welcome your enquiry with your product and production requirements.

Technical discussions start with the products you intend to make: regular material grades, size and wall-thickness combinations, cut lengths and quality requirements. These provide the basis for checking the line configuration, equipment interfaces and supply boundaries. New installations and retrofits need different information, and compatibility with retained equipment requires individual checks.

Our technical guides address practical questions in selection and production planning: comparing mill models, distinguishing motor power from incoming electrical capacity, specifying cooling conditions, and checking saw cycles and acceptance records. They support informed discussions; project parameters, pricing and delivery conditions follow the confirmed configuration and agreement.
