Plastic Process Equipment (PPE), Macedonia, Ohio, has introduced a portable, battery-powered hot tip sprue cleaner for melting thermoplastics from plugged sprues and runner systems. The cordless design enables use on multiple molding machines without the restriction of a power cord. When energized, the tip heats to 350°C (660°F) within 30 seconds. The hot tip sprue cleaner provides more than 35 minutes of working time per charge and can be recharged more than 500 times.
