Utilizing a wide array of laser welding techniques, Lake Region is well-versed in developing platforms for hundreds of product joining applications. Lake Region leverages its vast laser welding technologies to develop, validate and implement solutions for all medical device applications as well as critical non-medical applications.
Resistance welding is a process in which localized, electrically-generated heat and pressure are applied to create bonds between materials. This is a cost-effective method for joining certain materials without inducing significant stresses to assembly or subassembly. Lake Region utilizes strict process controls to minimize process variability and maximize robustness.
Lake Region typically solders medical materials with tin or antimony alloys as an economical method for joining components that will not operate under stress or elevated temperatures. Soldering uses a low enough temperature to leave joined components unaffected by heat. Lake Region has the materials process expertise to identify the proper solders, fluxes, thermal cycles and cleaning processes to ensure a sound solder joint.
Brazing is the process of flowing a melted metal alloy, typically copper or silver, across two metal components to join the materials. This is an economical joining method for components that do not realize high stresses or temperatures in service. Lake Region has the materials process expertise to identify the proper brazing alloys, fluxes or atmospheres, thermal cycles and cleaning processes to ensure a sound braze joint.
UV bonding is an adhesive process that cures materials using Ultra Violet light. This rapid process creates shorter cycle times. Lake Region leverages its experience in UV bonding at multiple facilities.
Adhesive bonding is a process used for joining any number of materials. It is often used in applications to join dissimilar materials in which typical bonding technologies are not possible. Lake Region utilizes a great number of technologies and is well-versed in adhesive bonding for medical device applications.
Crimping is the joining of components via mechanical means, often a bending or deforming process. Crimping is a common method for joining components into a functional assembly or subassembly and is ideal for small medical devices that have minimal joining options. Lake Region is experienced with exceptionally complex and small diameter crimped connections and offers in-house testing for strength and fatigue.
Swaging is a rotary hammering process used to reduce the diameter of tube and wire ends, which are then formed into a customer-defined shape with enhanced mechanical properties. This process does not produce chips or metal loss and can achieve very high deformations without intermediate annealing, producing the net shape in one operation. Common swaging applications include attaching radiopaque marker bands to polymer catheters. Lake Region leverages its strong expertise in swaging with in-house tool manufacturing, process experts and process automation. Lake Region can produce a highly capable, cost-effective swaging process for your end shaping needs.
Induction welding uses electric induction energy and forging pressure to join two materials, either metal or plastic. Induction welding can be controlled to quickly heat small areas, avoiding heating of adjacent material.
Ultrasonic welding is a process for joining similar and dissimilar polymer based components using ultrasonic energy and pressure. This process creates strong, reliable and potentially hermetic seals by melting the materials together. Lake Region is well-versed in process optimization and tooling development to achieve the desired joint performance with minimal flash and particulate generation. Additionally, Lake Region provides material selection and component design support to achieve the product performance at the lowest possible manufacturing costs.
Radio frequency (RF) welding utilizes radio frequency energy to melt and bond polymers, typically for large-volume film products such as blood bags and colostomy bags.
