Color delta tester( CR-10)
Offer parameter of ⊿E、l、a、b ,can accurately control color difference, contrast to samples and quickly and exactly adjust the match color of printing ink.

Life Cycle Testing
Our life cycle tester allows us to actuate a switch 1,000,000 times in less than a week. Life cycle testing is used to evaluate components and switch designs.

Peel Testing
In-house testing of adhesives allows us to determine the best adhesive for each application.

Environmental Testing
Temperature and Humidity cycling is the best way of predicting long term reliability of switches that will be subjected to harsh operating conditions.

Abrasion Testing
Taber abrasion testing is one of the best ways of quantifying the hardness of printed inks and is a good indicator of durability.

Two dimensions measuring instrument

The management of Bolin believes that training is a competitive advantage. Accordingly, we teach many classes at Bolin to help employees’ skill development. Most months, three or four of these classes are being offered.

Employee Orientation

– A one-session class that introduces new employees to Bolin and our Quality Policy and systems.

Quality Awareness Experience

– A four-session class that teaches employees basic quality improvement skills. Every Bolin employee takes this class during their first year of employment.

Mission:

Continuous Improvement – A four-session class that focuses on tools for continuous process improvement.

QES

– This ten-session class teaches additional problem solving techniques and details about the 14-step quality improvement process at Bolin. The class is a prerequisite to becoming a member of our quality improvement team.

Statistical Process Control 1

– A ten-session class that teaches basic SPC techniques.

Statistical Process Control 2

– An eight-session class that teaches more advanced SPC.

Cosmetic Inspection

– A four-session class that teaches cosmetic inspection as an objective skill.

Blueprint Reading

– This four-session class teaches the basics of blueprint reading.

Basic Math

– This class is a prerequisite to SPC. Candidates can test out of this class. It lasts several sessions until class members have mastered all of the math skills necessary to learn SPC.

Occupational English

– This class is taught to help non-native English speaking employees prepare for career advancement at Bolin.
