Stem seal for needle valve
Stem seal for needle valve
To optimize the operation of the needle valve VASP, it is possible to apply the T-VASP stem seal in order to create a dedicated chamber for retraction that is isolated from the air delivery channel in the cavity. This application can also be useful in case the VASP valve is intended to aspirate air from the cavity to create a vacuum before molding.

Mechanical lifter
Mechanical lifter
The lifters CAM are a simple and effective solution to release undercuts in injection molds. The movement of the blade is completely mechanical and guarantees high reliability, the DLC coating ensures low wear and self-lubricating function. Both body and blade can be machined to get the required geometry. Special sizes and double layout are available on demand.

Collapsible cores
Collapsible cores
The mechanical collapsible cores are made of an inner core and some segments connected by a properly designed guiding system. During the ejection phase the segments slide along the inner core performing a radial movement which allows to release an internal undercut. Internal undercuts on round, square or oval parts can be easily released during the ejection process. Multi start threads or a combination of right- and left-handed threads can also be released. The dimensional stability of parts injected using mechanical collapsible cores meets the highest requirements. An accuracy of ±0,02 mm can be achieved for both flatness and roundness.

Marking Unit
Marking Unit
The Marking unit allows for a quick front assembly and disassembly of a moulding insert. The system is made up by a body, which is fixed in the mould with a screw, and a hemispherical insert that can be easily placed into the body and tilted to the hooking position. The insert release is easily carried out applying a force close to the reference point. The magnet on the removal tool allows an easy extraction of the insert. The insert is available without markings, with standard recycling symbols or with special engravings.

Hydraulic gate cutting system
Hydraulic gate cutting system
The Octagon technology allows to separate the molded part from the cold runner during the molding cycle thanks to the axial movement of a cutter driven by a mini cylinder fed with high pressure oil.
The cut is made with the mold closed at the end of the holding phase. At this point the polymeric material is still hot, the operation is therefore not a real cut but a movement of material.
High pressure and accurate time control are required to perform a quality cut. Our GCM Control Unit makes it possibile.

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.

O-ring for high temperatures
O-ring for high temperatures
O-ring maximum working temperature changes with the type of fluid.
ERMANNO BALZI cooling components are equipped with FKM O-rings suitable to work with pressurized water or oil up to 150°C.

In case of applications requiring the circulation of fluids such as steam, pressurized water or oil at high temperature we suggest to apply O-ring made in special FKM compounds properly developed to guarantee better performance.
  • O-ring for steam or pressurized water suitable for working temperature up to 190 - 200°C and peak temperature of 220°C
  • O-ring for diathermic oil suitable for working temperature up to 200 – 220°C and peak temperature of 250 - 270°C
