Chih Hung Machinery Co., Ltd. was established in 1985 and has specialized in manufacturing laboratory testers that can be used to test plastic material and its related agents, such as plastic compounds, PVC, PP, PS, ABS, EVA, etc. Test Roll and Test Hot Press Forming Machine also can be used for heat stability test. In the inital stages, we supplied steam heating and electric heating models.
When the plastic industry was booming, I devoted my professional manufacturing technology
& experience to supplying the modern & high performance testers to customers and assisting the customers to upgrade production technology, pay much attention to product's R&D and QC, reduce
material's loss and cost, increase product's added value, ect. Moreover, to meet the high
temperature requirement of the industry that proceeds material R&D and technonogy research
engineering, we have specially developed and designed one Oil Heating Test Roll CR-OH-820
that has many features, such as hard chrome plating polishing roll, drilled roll, max temperature 250C for hot oil cycle heater, +/-1C temperature accuracy for roll surface, two roll at individually infinitely variable speed, knee-push safety emergency brake, central control panel , etc. It has become the equipment that pioneers and researchers of plastic industry in the world love the most.

Test Roll (CR-OH-820) can be used for the milling for a small amount of plastic compounds and related raw materials. It features with easy operation and high performance. It's mostly used to test the plastic property, quality, color matching, etc. of plastic mixing process and related material.

The stabilizer can use the Test Roll to do Milling Test and also can be added with Tio2 (TitaniumDioxide) to be mixed together and then works with the Aging Tester to do Static Stability Test.

Prosperity Machinery Co., Ltd. has the modernized factory and precision CNC equipment. Our concept, beilef and action are always the same. Our products' quality exceeds their value and is worthy of your trust and purchasing. We love serving people and world like to devote our love and gratefuiness.
