Why Choose the Automatic EVA Single-Color Foam Injection Molding Machine
Single-Color, Wide Station Range
The machine is designed for single-color EVA foam injection. It is available from 2 to 12 work stations, so the same machine series covers low-volume trial production and high-volume mass production.
Servo Motor and PC Control
The machine uses a servo motor system and a PC control system. The servo drive gives precise control over the injection speed and clamping position, while the PC control system manages the injection, clamping, and heating cycles.
Two Full Automatic Injections
The machine is equipped with two full automatic and high-efficiency injections, combined with a high-performance mould clamping system. This supports consistent injection and clamping across the production run.
About This Automatic EVA Single-Color Foam Injection Molding Machine
The Automatic EVA Single-Color Foam Injection Molding Machine is designed for single-color EVA foam injection. It is used to produce EVA midsole, sole, and various kinds of EVA foaming products. The machine injects the EVA material into the mold under heat and pressure, and the mold is held closed by the clamping system during the injection cycle.
The machine is equipped with two full automatic and high-efficiency injections, combined with a high-performance mould clamping system and PC control system. By using EVA as the raw material, the machine can produce midsole, sole and various kinds of EVA foaming products flexibly. The two injections supply the EVA material to the mold, and the PC control system manages the injection, clamping, and heating cycles.
The machine uses a servo motor system. The servo drive gives precise control over the injection speed and clamping position, which supports consistent part weight and dimensions across the production run. The PC control system provides the interface for setting the injection parameters and monitoring the production cycle.
The machine is available in two model series. The GW-260 series is available in 2, 4, 6, and 8 work station configurations, with a 330 × 600 mm mould-holder dimension and 250T clamping force. The GW-200 series is available from 2 to 12 work stations, with a 290 × 500 mm mould-holder dimension and 170T or 200T clamping force.
This automatic EVA single-color foam injection molding machine is an injection molding device. It is different from the hot press machines in our range, such as the GW-6004 and GW-6006 series, which use heated molds and hydraulic pressure to press and form a pre-formed sheet. The EVA injection molding machine injects the EVA material into the mold, rather than pressing a pre-formed sheet. It is also different from the double-color and multi-mode EVA injection molding machines, which use multiple injectors for multi-color production.
If your process requires single-color EVA foam injection with a wide range of station counts, this automatic EVA single-color foam injection molding machine is the appropriate machine. If your process requires double-color or multi-mode production, please refer to the double-color and multi-mode EVA injection molding machines.
Please contact us with your sole type, production volume, and required station count so we can recommend the right model for your production.
