Sensor module
Sensor module
Sensor module is a device developed to detect the presence of an insert in overmolding injection process.
The device is easy to apply and allows for a setting of the reading distance from the parting line. The sensor module is available with an embedded magnet.
Sensor module can be connected to the logic distributor LD - ...designed to deliver an enabling signal to the injection moulding machine when all the connected sensors are activated.

Insert removal
Insert removal
The insert removal EI is a mechanical device designed to enable easy assembly and disassembly of mold inserts even when clamped inside the injection machine. A bevel gear actuates a screw that tights and releases the insert. The bulky design allows good tightening torque and longevity of the mechanism.

Locking cylinder
Locking cylinder
The side-action CA locking cylinder is designed to withstand plastic injection force during the injection phase. Its compact design enables the whole part to be embedded into the cavity, reducing necessary mold dimensions while. The rod orientated against rotation allows for easy application in case of shaped cores. The cylinder can work with air without downsize of locking action.

Gas venting ejector pin SGDE
Gas venting ejector pin SGDE
The gas venting ejector pin SGDE incorporates the dynamic venting technology based on a simple mechanical system allowing the gas to escape from a venting hole that automatically closes under the pressure of the plastic flow front. The venting ejector pin can be placed inside the cavity where the filling pattern produces gas traps or at last filling point. The venting hole isn't affected by mold deposits, thanks to the high venting capacity counter pressure of the air inside the cavity is dramatically reduced.

New dynamic gas venting valve
New dynamic gas venting valve
The new dynamic gas venting valve SGD is an innovative solution able to help solving the most familiar effects of poor cavity venting. SGD is based on a simple mechanical system allowing the gas to escape from a venting hole that automatically closes under the pressure of plastic flow front. SGD can be placed inside the cavity where the filling pattern produces gas traps. The venting hole isn't affected by mold deposits, thanks to the high venting capacity counter pressure of the air inside the cavity is dramatically reduced.

Internal baffles
Internal baffles
Internal baffles can be easily fixed inside the cooling channel thanks to the proper tool. The rapid fitting technology allows ease of extraction, mechanical fixing and hydraulic sealing in holes oversized up to 0,4 mm. Internal baffles have been designed for large moulds to reduce the length of baffles and to optimize the thermal conditioning.
