Used Woojin Hydraulic Injection Molding Machines for Sale

Woojin Plaimm was founded in South Korea in 1985 with a singular focus on plastic injection molding technology. The company established a dedicated R&D center in 1999 and achieved a landmark milestone in 2000 by developing the first all-electric injection molding machine produced in Korea. Subsequent years brought further advances, including two-color (dual-shot) machines in 2004, PET preform systems in 2005, and stack-and-tandem mold machines in 2008. In 2014 a major new production facility opened in Boeun-gun with a capacity of approximately 6,000 machines per year, and an R&D subsidiary was established in Leobersdorf, Austria to drive next-generation series development.

Woojin's core product lineup centers on horizontal injection molding machines spanning a wide range of clamping forces and drive technologies. The TH Series is a versatile multipurpose hydraulic machine configurable for energy saving, high-speed injection, or electric-charge operation, and the TH500S is a well-known model in this line. The DL and DL-A5 Series are two-platen direct-locking machines covering medium to ultra-large tonnages from 450 to 3,000 tons. The TE and TE-K Series are fully electric machines using servo-motor-driven ball screws and LM guides for high precision and low energy consumption. The TB Series is an energy-saving servo-pump hydraulic machine, and the NC Series handles dual-color (two-shot) molding applications.

Woojin Plaimm machines serve a broad base of end-market industries. Automotive parts manufacturing is a primary focus, particularly for lightweight structural components where the company's Super-Foam microcellular foaming technology is applied. Electronics, consumer appliances, and mobile device components represent another major segment. Medical device and healthcare product molders rely on dedicated configurations of the TH-A5 and TE-A5 for clean-room-compatible, high-repeatability production. Packaging, household goods, and cosmetics manufacturers round out a global customer base of more than 10,000 accounts across over 40 countries.

Buyers seeking used Woojin injection molding machines are drawn by several practical advantages. The machines are built to a high standard of mechanical rigidity — Woojin controls much of its own manufacturing from foundry through final assembly — which translates to long service life and consistent shot-to-shot repeatability well into secondary ownership. The TH Series in particular has a strong installed base in North America, making parts and service support relatively accessible. Energy-saving servo-pump hydraulics and all-electric drive options also mean that even older Woojin machines carry lower operating costs than comparable conventional hydraulic presses, a meaningful factor in total cost of ownership calculations for used-equipment buyers.
