Food Industry Case Studies

PEEK roller used in beverage filling industry

PEEK guide block, roller and bottle clamp block are applied in beverage filling equipment. Canning equipment of Master Kong, UNI-PRESIDENT and others for green tea and black tea is widely using PEEK guide block.. Meanwhile, they are used in large quantity in canning production line in Coco cola.

PEEK Characteristics & Advantages

Environmental and innocuous.

PEEK itself is environmental and innocuous and has been certificated by FDA. It can be used in contact with food and has no contact duration limit.

Low hygroscopicity and hydrolysis resistant

It can work in the water and steam for a long time.

Wearing resistant

PEEK and its compound materials are of leading wearing resistance in plastics which is three times better than copper alloy.

Corrosion resistant

Food processing and packing equipment are designed as self cleaning to guarantee the quality of food and safety.Cleaning solutions are generally composed by acid and chlorine. PEEK has astonishingly stable chemical structure and has good corrosion resistance facing all kinds of organic and inorganic solutions, even in the high temperature. It solves the difficulty that metal and ordinary plastic can’t bear corrosion for a long time.

Self-lubricating

It can serve stable work without oil for a long time. This can avoid using of metal parts which need oil lubricant and bring contamination to packing machine and food. At the same time, the appearance of packing machine would be cleaner.

Easy to form

PEEK has good processing and forming characteristics.It can take processing procedures like injection molding, machining, milling, drilling,tapping, NC, CNC, etc to process all kinds of complicated special-shaped parts conveniently according to the drawings or samples of customers

High temperature resistant

Packing machine or food is normally disinfected by high temperature and lasers. The continuous using temperature of PEEK is as high as 260℃. It can maintain good mechanical strength even in 300℃, which can be heated in hot air furnace, digester, contact heater or microwave oven.Therefore, PEEK parts can bear repeated disinfection, including 200℃ autoclave disinfection, 143℃ flash disinfection,`Y-laser disinfection and ethylene oxide disinfection lamp. It won't lose mechanical properties and still has good stress cracking resistance.

Because of outstanding characteristics and advantages like wearing resistance, high temperature resistance, high strength, self-lubricating, etc of PEEK, we can guarantee the continuous using of parts on equipment for a long time and avoid shutdown of equipment caused by changing parts.
