Memory foam earplugs automatic production line is developed by our company after absorbing advanced experience at home and abroad and combining the actual requirement of polyurethane foaming machine production. Mould opening with automatic timing and function of automatic clamping, can ensure that the product curing and constant temperature time, make our products can meet the requirements of certain physical properties.This equipment adopts high precision hybrid head and metering system and distributor;Measuring system adopts servo inverter control, can ensure measurement accuracy stable operation.Through market research this production line has a saving materials, high yield, save labor and materials for the enterprise to achieve high efficiency of return, etc.

Specifications of ear plugs production line:

1.Low pressure polyurethane foam earplug production line, is specially designed as customer’s need.

2.This production line has about 17 moulds, and each mould has 48 holes.

3.you can choose more moulds, if you need more production capacity.

Figures of ear plugs production line:

Slow rebound earplug automatic production line is a new polyurethane earplug production line that we manufacture by learning advanced technology from home and abroad and by referring to the actual demand of the production of polyurethane foaming machine. It is equipped with automatic timing and die-opening and die-closing function; it may ensure product curing and constant temperature time so that the product is able to meet certain physical requirements. This equipment adopts high-precision mix-head, metering system and distributor; the metering system adopts servo inverter control to ensure metering accuracy and stable operation. According to the market investigation, this production saves materials, has high yield, saves labor and materials, and therefore achieves high efficiency and high return.
