Compression Molding Machine, Vacuum Press

The TMP Inc. TECHNI-MOLD Hydraulic Compression Press for molding rubber & silicone parts has been for over thirty years TMP's principle product line supplied to hundreds of satisfied and repeat customers. TMP has lead the industry incorporating technological advancements to these presses and the molding process.

Types of Compression Molding Processes:

TMP offers a variety of compression molding machine types and associated automation for compression-molding of rubber and silicone:

Straight Compression Molding
Hydraulic Transfer Presses
Hydraulic Vacuum Press

TMP Standard Hydraulic Compression Molding Press Components:

Press Frame

Slab-Side type Press - A Vacuum chamber can be readily incorporated into this frame design
Four-Post type presses - TMP uses high-tensile rods with over-size diameters, which are identically machined with square shoulder to maintain crosshead parallelism
C-Frame and Window Frame types are available for special applications

Platens

TMP Electrically-heated platens are uniquely designed for uniform heat distribution and temperature control. TMP has designs for high-temperature applications.
TMP Oil-heated platens are also available. This method provides very accurate and uniform temperature over a wide range of molding applications.
TMP Steam-heated platens are efficient for temperatures to 360°F (150PSI) TMP platens have individual steam traps for better uniformity over systems with a single trap.

Press Ram & Main Cylinder

TMP's Ram-Cylinder designs are a heavy duty and rated to 3000PSI. The designs contain special guiding and sealing to provide accurate alignment, reduced wear.

Press Crosshead

Machined from thick solid steel plate to minimize deflection.

Moving Bolster Assembly

TMP's Bolsters are machined steel, ground flat and parallel. Bolster guides are heavy-duty and are temperature-compensating in their configuration, allowing constant clearances to maintain parallelism.

Hydraulic System

The TMP press Hydraulic System is a proven for its efficiency and long-term reliability. These hydraulics combined with TMP's advanced controls provide press control, accuracy and flexibility unmatched in the industry. The system includes:

Hydraulic unit, consisting of a steel constructed reservoir, pump, motor. Features are built-in such as slow decompression, to eliminate hydraulic shock and extend operating longevity.
Ram pre-fill system with side cylinders for fast closing speeds A "kidney loop" for proper filtration
Ram pressure control of the machine using CPS Controls is accomplished by a very accurate and maintenance-free proportional closed-loop hydraulic pressure control valve and associated electronics.
Dual transducers are used for back-up and reliability of pressure control to maintain calibration.

TMP Advanced Controls Systems

TMP offers two standard Controls packages for molding rubber and silicone. The BPS Control Package, although basic, provides programmable control of pressures, times, allowing for bump cycles, and platen temperature control. It includes a microprocessor and an LCD display to enter recipes and compare actual process values to pre-programmed settings.

The industry's most versatile system is the TMP CPS Compression (Vacuum) Press Control System. This is a PLC-based system designed to improve product quality through better pressing accuracy, repeatability, versatile process control programming and monitoring of data for analysis. Components of the system include:

NEMA-type enclosure mounted to the side of the press.
PLC to provides for internal control (PID) of all the temperature loops/zones, machine diagnostics, log sequences, etc.
Color TFT Touch-screen Interface for input and display of all machine parameters and process data.
Visual Alarms for temperature and pressure faults.
The structure of the PLC offers the capability for connections to a highway communication system/network (LAN) or other computer systems

Combined with electronic proportional valving and linear displacement transducers, control of compression rates and/or velocities, as well as pressures and times, is attainable through the operator interface.
