Hydraulic Press Manufacturing (HPM) was a 135 year old Ohio plastics company, but it went bust in 2009.
However, you can still buy products with the HPM brand, but it’s not a U.S. company anymore.
In 2011 a Chinese company called Guangdong Yizumi Precision Machinery, bought all the rights to HPM and all its products. Production has been started in southern China.
The Chinese company says they’ve even hired former U.S. employees of HPM. They are setting up shop in the United States and already have contracts in north America worth $3 million USD.
