Thermoplastic Resin and Glass Wool Cleaning Agent for Molding Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning agents with glass fibers for molding machines do not provide a quick and even removal of residues, leading to inefficient cleaning and potential defects in molded articles due to uneven residue distribution.
Innovation Solution
A cleaning agent comprising thermoplastic resin and glass wool, with 50 to 80% glass wool by weight, not treated with lubricant or silane coupling agents, is used to heat and supply into the molding machine for effective residue removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cleaning agent containing glass fiber is used for cleaning, then cleaning power is improved, but residues are unevenly removed and it takes time for the removal until influence of the residues is eliminated
Solution Approach 1:
The patent changes the physical parameters of the cleaning agent by using glass wool with specific fiber diameter (5-20 μm) and length (3-10 mm) ratios, and controlling the glass wool content at 60-80 mass%, which improves both cleaning efficiency and residue distribution uniformity, reducing the time needed to eliminate residue influence
Solution Approach 2:
The patent creates a composite cleaning agent material by combining thermoplastic resin with glass wool, where the glass wool provides cleaning function while the resin matrix ensures uniform distribution and flow characteristics, resolving the contradiction between cleaning power and residue removal uniformity
2Reliability
If a cleaning agent containing glass fiber is used for cleaning, then cleaning power is improved, but manufacturing efficiency is reduced due to incomplete residue removal affecting next molding
Solution Approach 1:
By optimizing the glass wool fiber diameter to 5-20 μm and length to 3-10 mm, and setting glass wool content at 60-80 mass%, the cleaning agent achieves thorough residue removal that allows next molding to proceed without complete residue elimination, thereby improving manufacturing efficiency while maintaining cleaning power
Solution Approach 2:
The cleaning agent with optimized glass wool parameters performs preliminary cleaning action that sufficiently removes residues before next molding, preventing appearance defects and enabling continuous production without extended cleaning time, thus improving productivity
3Productivity
If residues are not completely removed when resin materials are exchanged, then manufacturing efficiency is improved, but appearance defects occur in molded articles
Solution Approach 1:
The patent optimizes glass wool parameters (diameter 5-20 μm, length 3-10 mm, content 60-80 mass%) to achieve a balance where sufficient residue removal occurs without requiring complete elimination, preventing appearance defects while maintaining manufacturing efficiency
