Saves on Production Time and Costs, Boosts Productivity

Bright Burnishing Tools is a manufacturer of burnishing tools in India. They were using silver brazing process to join the tool shaft to the holder. The silver brazing material is expensive and the process needs very skilled operator and is time consuming. Additionally, the process involves heat and brazing flame that might bring safety concerns for the operators.

Excellent Bonding to Low Surface Energy Polyolefin Substrates Saves Rejections

A multinational customer was planning production of coffee makers for their export markets. Customer used a competitive instant adhesive for bonding the rubber bead to PP (polypropylene) in carafe. Carafe is the glass container used to brew, hold and serve coffee and has a PP top and handle.

Loctite® Dispensing Equipment Provides Easy and Precise Application

BPL Compressors, India manufactures Hermetically sealed compressors for refrigerators. BPL were using a competition epoxy to bond and seal PBT suction muffler in the compressor. They were getting 9% rejections due to leakage and parts had to be reworked. In a large production volume these rejections and reworks add significant costs to operation costs.

Customer Also Gains Higher Productivity through Loctite® Dispensing Equipment

Invensys, NSW, Australia makes diastat sensors for in the appliance industry. As the final operation, customer phenolic cap needs to be bonded to steel thermosensor. Customer worked with Henkel Engineer for a solution for this new design. Loctite 4210 High Temperature Instant Adhesive was successfully tested for the application. Loctite Analog Syringe Dispenser 98417 with 30ml Syringe Kits 97244, 97245 was configured to accurately dispense the adhesive. Loctite 7070 ODC Free Cleaner was used to clean the parts prior to bonding.

Allows Step Motors to be Used in Sensitive Semi-Conductor Applications

In some semi-conductor applications the small amount of EMI emitted by step motors disrupted precision instruments. To eliminate the EMI, the stators needed to be grounded to the housings. After extensive testing, Lin Engineering found that Loctite® 3888™ two-part electrically conductive epoxy adhesive was selected as the optimum solution. It completely eliminated the EMI with the added benefit and also structurally reinforced the motor which has allowed Lin Engineering step motors to be used in sensitive semi-conductor applications.
