Rainbow establishes standard component and model database for tool design, also the database for lessen learn and success cases. 

 Success Case:

Problem Description: normally for this kinds of part, its production cycle time is about 60 seconds, which causes of high cost of production.

Reason Analysis: through investigation and analysis, there’s room of improvement and optimization for injection gate and cooling circuits for tool, which is based on Rainbow years of experience and previous lessen learn.

Action Implemented: adjusted injection gate with best position, and designed separate cooling channels for tool. Though there’s cost increased due to the milling difficulty enhanced. Yet it shorten the injection cycle time from 60s into 48s. Tool right now is running stably and smoothly without problem in Hella production plant. This is one of examples that Rainbow help our customers to save money as much as possible and support customer in our efforts to bring maximum profit.
