Current Stock:

The Spectrum ULTRA Series High Tonnage thermal press is our new advanced compact bench top or table top system with easy to use COLOR touch screen controls (HMI). This more advanced model provides closed loop process controls and process parameter windows and also allows for additional options and accessories for better control and use while heatstaking.

Available in either 120V or 240V (50/60Hz) and with three different force models the Spectrum Ultra Series High Tonnage Heatstaking Press system is an ideal system for all thermal secondary and sealing operations requiring high tonnage forces. Press forces range from 1-1/2 to 5 tons depending on model chosen.

Gross Head Adjustment:
Designed with a rack and pinion beveled gear mechanism for ease of moving head up and down to next position/application


Multi-Zone Temperature Controllers:
The use of the multiple temperature zones allows individual control of each staking or insertion tool (±2°F) when it's required in an application. The high Tonnage series systems can be supplied with unlimited individual temperature zones.

Digital Dwell Timer:
For precise control of the staking application once contact has been made with the product. This timer provides timing from .01 seconds up to hours. Programmable time ranges include hundredth of seconds, tenths of seconds, seconds and minutes.

Slow Speed Control:
Incorporated in the High Tonnage series systems is a pneumatic check unit/slow down device. This device is adjustable so it can be positioned anywhere within the stroke of the heated tools. Generally the tooling head contacts the speed control just prior to the heated tooling making contact with the plastic stud or insert to be staked. The speed control device is adjustable to control how fast or slow the stake is being performed.

Mechanical Depth Stop:
Is used for fine adjustments of final head down position.

Post Cooling Feature:
Our unique post cooling feature is used on staking applications to insure a consistently tight assembly and prevent plastic adherence or stringing on the hot tool. The post cooling air line is located adjacent to the heated tip and is adjustable in cooling time and air flow to the tool. This feature allows us to shorten cycle times by using elevated temperatures to "remold" the plastic part through use of true melting and cooling much like a molding machine.

Spring Loaded Plunger:
Mounted to tooling head to apply pressure to work piece prior to and after staking.

Multi-Point Tooling Probe:
Our custom designed 340 watt thermal probes have an integral thermocouple at the heater/tip interface for optimum temperature control of the process tool. The probe has a 1/4-28 tapped face to accept interchangeable tips. The High Tonnage series systems can be supplied with multiple probes per temperature zone or an unlimited amount of probes, each individually controlled. 

Optical Touch Buttons:
Ergonomically designed photoelectric switches eliminate hand, wrist and arm stress associated with repeated mechanical switch operation. Because no physical pressure is applied, risk of carpel tunnel syndrome is reduced and operator productivity and comfort is increased.

Pre-Heat Option:
stops travel at the insert to allow the inserts to pre-heat, then drives them in. Eliminates hoop stress and cold press-in.
