Four months after it debuted at Chinaplas in Shanghai, a new series of all-electric injection molding machines will be coming stateside, offering servo-driven injection, dosing, and mold movement but featuring a hydraulic accumulator for auxiliary axes like core pulls, ejectors, and nozzle movement.

 

Absolute Haitian, Worcester, Mass., www.absolutehaitian.com, the exclusive sales and service partner for Ningbo Haitian Machinery Co. Ltd., announced that this fall it will begin offering the Zhafir Zeres series of molding machines, initially carrying presses with clamping forces of 45 and 259 tons. Zhafir is Haitian’s self-described “premium” brand of injection molding machines, launched in Germany in 2005.

 

The Zeres machines are said to be structurally identical to Zhafir’s popular Venus II Series of injection molding machines, of which the company reports selling more than 4000 globally. At Chinaplas, the machine made its debut molding an automotive component from 30% glass-filled polyamide.

 

The full Zeres line is available in clamp sizes from 400 to 2,300 kN (40 to 260 tons). Haitian says the machines offer injection speeds of 200 and 160 mm/sec (7.87 and 6.29 inches/sec). The 200 mm/sec speed applies to machines up to 430 tons, with 160 mm/sec speed for higher clamping forces. An optional high-speed unit ranges to 350 mm/sec (13.77 inches/sec) injection speed.

 

The hydraulic accumulator utilizes a variable pump to optimize energy efficiency. The clamping unit offers programmable hydraulic core pulls at the moving platen, and high-speed ejector coupling, which reportedly reduces set
