Drader Injectiweld

Drader Injectiweld

Drader Injectiweld uses heat from the welding tip to pre-plasticize the welding surface of the thermoplastic. Molten plastic is immediately injected sub-surfacely under pressure, into the weld area to fuse the plastic together and form a sound weld. Since the orifice in the weld tip is submerged, surface preparation is not necessary and virtually no oxidation takes place during the welding process. The result is an efficient quality weld.

Fabricating: Injectiweld is easily adapted into production and assembly applications. The one-hand operation of the Injectiweld allows the user to manipulate the parts to be welded with the other hand. The welder can then free form product for faster turnover and production.

Prototyping: Products can be designed and developed using the Injectiweld. The strong welds achieved using the Injectiweld lets welded prototypes be used in real life tests. The Injectiweld is capable of producing welds as small as 1.5 mm for inconspicuous welds and up to 15 mm for added weld strength.

Repair: The combination of heat and pressure from the Injectiweld produces quality welds on previously unrepairable parts, allowing them to be fixed and put back into service. The Injectiweld is utilized in various industries such as: materials handling, lining, transportation, safety supply, and custom repair.

*Two new accessories which now come with each new “red body” Injectiweld are the Stand and a Heat-Resistant Glove (singular, not a pair of gloves). Accessories also available for individual sale.*

Materials that can be welded with the Injectiweld
The following table lists materials commonly welded with the Injectiweld. While many thermoplastics are weldable with the Injectiweld, some resins have not been tested extensively and therefore do not appear on the following list. Note the weld temperatures are specific to the Injectiweld system.

Material	Description	Injectiweld Weld Temp in °C	Injectiweld Weld Temp in °F
HDPE	High Density Polyethylene	265	510
LLDPE	Linear Low Density Polyethylene	265	510
HMWPE	High Molecular Weight Polyethylene	280	536
PP	Polypropylene	280	530
ABS*	Acrylnitrile Butadiene Styrene	265	510
PS	Polystyrenes	255	490
PVDF*	Poly vinyl difouride	300	572
PA*	Polyamide 6 (nylon)	300	570
PC*	Polycarbonate	300	570
PU	Polyurethane (thermoplastic)	300	570
Santoprene	TPE Thermoplastic Elastomer	280	530
X-Linked PE*	Cross-linked PE (See Special Treatment)	300	572

* Some materials are hygroscopic (i.e. they absorb moisture from the surrounding environment). When hygroscopic welding rod melts, the moisture boils. It will show up as a ‘bubbly’ appearance on the weld. To avoid this, dry the welding rod before welding. Drying times vary depending on the drying equipment, the amount of welding rod, its moisture level, and outside humidity. See Snap on Preheater flyer above in Video and Docs tab or use an inexpensive food dehydrator.
