Strategies for learning

They say that companies who cultivate a clear historic perspective move farther and more effectively into the future than those who do not.


Kim Union fondly recalls the time when they only have a production line for thread rolling machines. But since thread rolling dies plays a very important factor in the thread rolling method, there was a need for thread grinding. As what President Yu said, "What is the best way for producing thread rolling dies but through thread grinding."


Kim Union narrates how they did research on "thread grinding machines" in the market. There was no internet during the 1970s, no email and even fax. Therefore, they decided to import Swiss-made Reishauer thread grinding machine. It was a big risk since the price of the equipment was very high, and they did not have the experience in grinding but they believe that thread grinding is the correct way of producing thread rolling dies. To cut the long story short, this was how Kim Union started to produce thread rolling dies.


Fundamentals of thread rolling machines
In Taiwan, majority of parts are outsourced and assembled into complete machines in the factory, and Kim Union is not an exception. Therefore, before the parts are assembled at the factory, Kim Union will arrange for an accuracy inspection, and once the standard is met, the small parts will be combined into big parts, and then finally the entire thread rolling machines will be assembled.


In terms of raw materials, Kim Union chooses cast iron parts for the thread rolling machine's body rather than steel plate assembly. Cast iron parts with a high mass characteristic can considerably alleviate the vibration problem that occurs during machine operation.


Kim Union is meticulous when it comes to its assembly process. In addition to accuracy check, the body must go through scarping to increase the oil content. The transmission gears, worms, and bearing shaft parts are also ground and shaped by Kim Union's own screw grinder and gear grinder.


Kim Union's machine accessories are all well-known brands. The motor is either Siemens or TECO, while the inverter is the best-selling Delta in Taiwan, whereas the transmission bearing is a well-known brand, such as NTN, etc. In addition, Kim Union ensures the quality of its thread rolling machine by matching the entire package.


Personnel development

New technologies are revolutionizing the modern workplace and market. Skills training can help an enterprise stay at the forefront of innovation and creativity.


Kim Union believes that all of its staff must first be aware of their products and the quality they offer. For instance, if a staff is assigned to the assembly of thread rolling machines, he must pay attention to precision.


The company therefore recognizes that a good and knowledgeable engineer will lead another two less experienced staff. The skills learned from the proficient engineer will be passed on to the younger generation. Kim Union also emphasizes that an employee with sufficient professional skills will have the opportunity to be assigned overseas.

Currently, Kim Union has three factories in all. The Taiwan main production facility produces both thread rolling machines and thread rolling dies; while the two factories in China: Central China: Shao Xing and South China: Dong Guan creates thread rolling dies.

Competitive advantage

Kim Union’s 50 plus years of experience in thread rolling machine manufacturing combines technology and design to orchestrate meaningful milestones for everyone who interacts with their brand, UNIFY — from customers and prospects to employees and partners — at every stage of their journey.
