Laminating Device Buffer Hardness Gradient Resin Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing laminate molding devices, stress concentrates at the ends of the laminate during pressurization, causing resin to flow outside from the side surfaces.
Innovation Solution
A laminating device with a buffer system where the hardness of the peripheral part is higher than the central part, preventing resin flow from the laminate ends during pressurization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a uniform buffer layer is used between the plate-form member and pressurizing block body, then the structure is simple and easy to manufacture, but stress concentrates at the ends of the laminate causing resin to flow outside
Solution Approach 1:
The buffer layer is designed with non-uniform hardness distribution where the peripheral part has higher hardness than the central part. This local quality variation allows the peripheral region to resist stress concentration and prevent resin flow, while the central region maintains adequate cushioning properties. The gradient in hardness properties directly addresses the stress concentration issue at laminate ends without requiring complete structural redesign.
2Manufacturing precision
If the peripheral part of the buffer has higher hardness than the central part, then resin flow from laminate ends is prevented, but the buffer structure becomes more complex
Solution Approach 1:
Instead of changing the fundamental structure of the buffer layer, the invention modifies the hardness parameter across different regions. By controlling the hardness value to be higher at the periphery and lower at the center, the buffer achieves differential mechanical properties that prevent resin flow while maintaining a relatively simple overall structure. This parameter-based approach avoids complex multi-component designs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively prevents resin flow from the side surfaces of the laminate by distributing pressure more evenly, ensuring consistent laminate formation.
Implementation Method 1
a hardness of a peripheral part of the buffer is higher than that of a central part of the buffer, whereby it is possible to prevent resin in the vicinity of an end of the laminate from flowing outside

AI summary
In a laminating device (3) that pressurizes a laminate (A4) including a substrate layer (A1) and a resin layer (A2) between opposing boards (312, 314) at a predetermined temperature, in at least one of the boards (312) and (314), a buffer (327) is provided between a plate-form member (328) forming a pressurizing surface (328a) and a pressurizing block body (323) or (324), and a peripheral part (327b) of the buffer (327) has a hardness higher than that in a central part (327a) of the buffer (327). Accordingly, it is possible to provide a laminating device and a lamination method capable of preventing resin in the vicinity of an end of the laminate from flowing out from a side surface of the laminate when the laminate including the substrate layer and the resin layer is pressurized in the laminating device.
