Productivity improvement with Bossard engineering

The customer, a prominent electrical and electronic equipment manufacturer in China, specializes in producing a wide range of products, including high-voltage devices, low-voltage devices, transformers, switchboards, PLCs, inverters, and automation devices.

Opportunity

The customer seeks to enhance production efficiency and optimize fastening applications with the assistance of Bossard's Expert Teardown service

Challenges

Some of the customer's challenges in their low productivity assembly process, including:

1. Inefficient nameplate attachment.

2. Low efficiency caused by the use of anti-galling grease applied to stainless steel fasteners.

3. Reduced efficiency due to the application of thread anti-loosening glue on the screws.

Actions taken 

To address these challenges, the following actions were taken: Consideration of using speed rivets instead of semi-screws for faster installation, replacement of Loctite-LB 8150 with Everlube 620C as a pre-lubricant alternative and the utilization of pre-coated patches as a convenient and reliable sealing alternative to Loctite-243.

Customer benefits

Through engineering services, increasing customer stickiness by helping the customer to overcome the stainless steel fastener galling issues can be achieved. 

Additionally, the thread-locking glue is applied more evenly, resulting in a good anti-loosening effect. Production efficiency improvement 30% with Decease 4% cost and reduce costs by 51%,translates to 4,945 working hours annual. Savings equivalent to 2.4 headcounts.
