Injection Molding: Low-Cost Structural-Foam Press for Pallets
Wilmington Machinery’s latest is built to compete with Asian machines in this size range.
Wilmington Machinery has introduced what it believes to be the lowest-cost U.S.-made structural-foam machine for molding pallets. It’s positioned to compete on price with Asian-built machines of comparable capacity. The new Lumina Pallateer Model PM-1C has 350-ton clamp and ability to mold pallets up to 48 × 52 in. in size and weighing up to 40 lb. The two-stage (extruder/accumulator) injection unit has an extruder capacity of 1200 lb/hr of HDPE, sufficient to producer 30 pallets/hr.
Wilmington Machinery Lumina Pallateer Model PM-1C in single-nozzle (l.) and classic multi-nozzle structural-foam versions.
The machine boasts small footprint and low energy consumption. Its hybrid design incorporates servo-electric extruders and hydraulic injection and clamping. The 30:1 L/D extruder has an injection port for nitrogen gas and can process up to 100% recycled flake. Two versions are available—single-nozzle and “classic” multi-nozzle structural-foam manifold (both are shown here). Hot-runner molds, robots, and other accessories are available from Wilmington, along with training.
It may seem like a dull topic, but it will overcome the emotional experience that follows when you put a new mold into a machine and you find out there is not enough barrel capacity to make a full shot.
Over the past decade, soft-touch overmolding has radically changed the look, feel, and function of a broad range of consumer products.
Producing plastics parts with undercuts presents distinct challenges for molders.
