Thermal Probe
MATP™
Model TT39

Thermal Probes heat the staking post/insert while applying pressure axially to permanently seat the parts.  Advantages of the thermal staking/inserting process include:

• Reliable permanent inserts
• Multiple level inserting/staking
• Multiple size inserts
• Quick installation and adjustment
• No whitening when degating
• No particulates or noise
• Better cosmetic appearance when staking and swaging
• High tolerance to mold release, colorants and other additives
• Tolerant of resin grade variations and regrind percentages
• Low initial equipment cost
• Handles slippery thermoplastics
• Easier maintenance in a low-tech environment

Features

• Uses standard grid mounting hole pattern
• Fork permits easy adjustment of lateral or radial position
• Integrated ceramic insulation disk
• Built-in height locking adjustment is easily accessible even when probe is hot
• Socket and shaft made of Copper Alloy to reduce thermal mass and heating time
• Accommodates standard 12 mm heating coils
• Locking swivel adjustment permits adjusting position - sensitive tips without disturbing the height adjustment
• Probe shaft has standard 1/4-28 threads to allow use of existing tips
• Quick configuration and alignment minimizes production downtime

Applications

Thermal probe applications include heat staking, inserting, embossing, date coding and degating.

Automotive industry for door panels, map pockets, and light-pipe staking.  Medical applications include blood-processing equipment, chemical pumps, fittings, flow meters, IV drug delivery and surgical instruments.  Consumer Product applications include personal computers, portable telephones, laser printers, copy machines, video games, speakers and appliance components.  Industrial applications include conveyor systems, gears, pulleys, couplings, and motor housings.  Thermal presses are also used in Toy Manufacturing and the Sporting Goods industry.

Dukane thermal probes can work with a variety of materials including most amorphous and semi-crystalline thermoplastics as well as liquid crystal polymers.  Some difficult to weld plastics are well suited to the thermal process including lubricious materials such as PTFE.  Soft thermoplastics such as PE and PP react favorably to thermal inserting along with brittle materials such as 50% mineral-filled PPO (Ryton) which flakes when subjected to ultrasonics.  Call Dukane for a complete list of materials suitable for thermal inserting/staking.
