Sandwich Press Plate with Replaceable Embossing Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing press plates and endless belts used in wood-based panel production face issues with wear and tear due to abrasion-resistant particles, leading to frequent reworking and eventual instability, and inadequate heat transfer during the pressing process, resulting in high production costs and limited lifespan.
Innovation Solution
A press plate or endless belt design featuring a carrier body connected to an embossing body via a high-temperature-resistant adhesive, allowing for the embossing body to be easily replaced when worn, while the carrier body is reused, and using magnetic or metal-powder-doped adhesives for improved heat transfer and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If press plates are made from sheet steel with surface structuring, then the surface structure can be embossed into wood-based panels, but the press plates wear out quickly due to abrasion-resistant particles and require frequent reworking
Solution Approach 1:
The press plate is divided into two separable parts: a durable carrier body and a replaceable embossing body. The carrier body retains the surface structure while the embossing body absorbs wear from abrasion-resistant particles. When worn, only the embossing body needs replacement, extending the overall service life of the press plate assembly.
Solution Approach 2:
The embossing body is designed as a consumable component that can be discarded when worn and replaced on the same carrier body. This allows recovery and reuse of the expensive carrier body while discarding only the cheaper embossing body, reducing refurbishment costs and frequency.
2Temperature
If traditional adhesives are used to attach the embossing body to the carrier body, then the structure can be assembled, but heat transfer is inadequate during the pressing process
Solution Approach 1:
The adhesive is formulated as a composite material containing metal powder particles distributed within the adhesive matrix. This composite structure combines the bonding properties of the adhesive with the thermal conductivity of metal particles, enabling effective heat transfer through the adhesive layer while maintaining structural integrity.

Function Achieved in This Case
This design significantly reduces material waste and production costs by allowing the carrier body to be reused multiple times, with only the embossing body needing replacement, and ensures effective heat transfer during the pressing process, extending the lifespan of the press plates and reducing refurbishment needs.

AI summary
The present invention relates to a press plate 1 or continuous strip for embossing materials, in particular wood-based materials or plastic materials, by means of surface texturing. To significantly reduce manufacturing costs and material usage, the invention proposes the use of a sandwich body consisting of a carrier body 10 and an embossing body 11, these being intimately bonded to one another by means of an adhesive 12. By appropriately selecting the adhesive, it is possible to reversibly break the bond at any time using a solvent, thus enabling the replacement of the embossing body 11.
