Several different welding/bonding processes can be used to join two materials together in a secondary operation. The selection of a specific process begins during the design phase. Part geometry along with the desired functional or structural requirements, will help dictate the process best suited for joining the materials. As the assembly process is developed, specific part geometry changes may be required to aid in the welding/bonding process chosen.
Superior adhesion solutions
A process of joining two plastic parts together by spinning one part against another, creating friction heat and melting material at the joining surfaces. Pressure is applied and the spinning stops, cooling the material and joining them together.
A process of joining two similar material surfaces together, by heating the entire surface area using a heated plate, then contacting the parts together utilizing pressure while allowing to cool and bond.
Vibration welding physically moves one of two parts under pressure, creating heat through surface friction that melts and welds the parts together.
Sonic welding is the joining of two pieces through the using of High frequency vibration. The energy of the vibration is transferred to the “weld joint” and heat is generated while applying pressure.
Electro Magnetic Assembly Bonding is a process that that utilizes high frequency energy to excite susceptor particles in a rope like plastic material. The material is melted in a precise location or bond line to join plastic materials together.
Chemical adhesives can we used to join two dissimilar materials together. Many different types of bond strength can be created utilizing different adhesive types and grades.
A process of joining two parts together utilizing heat to deform a boss or post. The post fits into a hole and extends above the surface, allowing the heat staking to deform the post. Once the post is deformed, it prevents the two parts from separating.
