Mold Material Gas Discharge Heating for Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the processing of mold materials, the adherence of supports to the mold material can result in adverse effects due to gas generation, leading to insufficient bonding strength.
Innovation Solution
A method involving the heating of the mold material layer to discharge gas before adhering the support, which includes setting a suitable temperature range and environment, such as 100°C to 250°C under atmospheric or reduced pressure, to prevent gas generation and enhance bonding efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heating is applied to the mold material to adhere the support, then bonding strength is improved, but gas is generated from the mold material causing adhesion failure
Solution Approach 1:
The patent applies preliminary action by heating the mold material to discharge gas before the actual adhesion process. This pre-treatment removes harmful gases that would otherwise interfere with bonding, allowing subsequent heating to achieve strong adhesion without gas-generation problems.
Solution Approach 2:
The patent segments the heating process into two distinct stages: a first heating step for gas discharge at lower temperature, and a second heating step for adhesion at higher temperature. This segmentation allows each step to optimize for its specific purpose without the negative effects of the other.
2Strength
If heating temperature is increased to improve adhesion, then bonding strength increases, but gas generation from mold material worsens
Solution Approach 1:
The patent divides the heating process into two temperature stages: first heating at a lower temperature range to discharge gas, and second heating at a higher temperature range to achieve strong adhesion. This segmentation resolves the contradiction by separating the temperature requirements for gas discharge and adhesion into distinct sequential steps.
