Henkel LOCTITE® TECHNOMELT, formally branded as Macromelt®, is a line of polyamide and polyolefin thermoplastics that are ideal for protecting electronic assemblies. TECHNOMELT resins are 100% solids, one-component systems, maximizing yield and minimizing loss or waste.
Low pressure molding is an encapsulation process used to over-mold electronic components and circuit boards for protection against environmental exposure. Processing cycles are very short compared to other encapsulant systems, typically taking less than one minute per mold cycle.
Reduced cycle time
Low viscosity materials
High temperature, shock, and solvent resistance
No curing required
Suitable for sensitive electronic parts
Precise, watertight encapsulation
Excess material can be reused
Low labor cost
With sustainable bio-based formulas, TECHNOMELT hot melt adhesives can be applied to a wide range of industries and applications. Below are examples of our most popular adhesives:
TECHNOMELT AS 4226
TECHNOMELT PA 668
In many cases, TECHNOMELT hot melt adhesives are a simpler, faster alternative to other bonding processes, available in a range of chemistry platforms depending on the manufacturing process and product requirements. Browse our online product catalog for all available TECHNOMELT products.
Ellsworth Adhesives offers low pressure molding services that combine the superior performance of Henkel LOCTITE® TECHNOMELT thermoplastics with the versatility of Mold-Man® Machines low pressure molding systems. Allow us to evaluate and engineer the best product solution for your application. From prototyping to production, our goal is to make your process faster, accurate, and more efficient.
1) Material Selection
Our skilled engineers will help you find the right hot melt for your application based on hardness, elasticity, chemical and environmental resistance. A moldflow analysis is performed to analyze material and its behavior in areas like plastic flow, pressure drop, and fill time.
Moldsets are manufactured from the highest quality, aircraft grade 7075 aluminum for strength, durability, and material consistency. Prototypes allow for any modifications or additional testing to be made prior to full production runs.
Mold-Man® Machines are easy to operate and ideal for high volume production. Every machine is configurable and has capabilities for one or two component materials. They have a long service life and require minimal maintenance. Learn more about MoldMan Systems™.
Your electronic device is now protected against environmental and chemical exposures. It has excellent insulation, strain relief, and improved flexibility. You now have the ability to manufacture your product more efficiently by increasing productivity and reducing waste compared to traditional potting applications.
