Fiber-Containing Material Molding Tool for Clean Edge Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing fiber-containing materials in wet molding processes suffer from undesirable fiber deposits that lead to protruding edges in finished products, requiring rework, resource-intensive cleaning, and machine contamination, with spray bars failing to reliably clean edge sections effectively.
Innovation Solution
Integrate a spray arrangement into the suction or pre-pressing tools to dispense a medium in a targeted manner, aligning fibers in the edge section, using outlets that are specifically designed and aligned with the opposing tool to form a clear edge without protrusions, and incorporate a stripping lip to scrape off excess fibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a spray bar is used to clean the edge section, then fiber alignment is attempted, but the cleaning is unreliable and resource consumption increases
Solution Approach 1:
The spray arrangement is designed with outlets that are specifically positioned and oriented to target only the edge section of the mold body, rather than spraying the entire surface. This localized approach ensures that the medium is applied precisely where fiber alignment is needed, improving edge formation quality while reducing overall resource consumption compared to full-surface spraying
Solution Approach 2:
The spray arrangement is integrated into the tool structure as a discrete component with multiple outlets distributed along the edge section. This segmentation allows the spray system to be independently controlled and positioned, enabling reliable cleaning of the edge section without wasting resources on areas that do not require treatment
2Ease of operation
If a spray bar moves along a linear axis, then cleaning is attempted, but different relative speeds at differently aligned stripping edges cause unreliable cleaning
Solution Approach 1:
The spray arrangement outlets are designed with adjustable or variable positioning along the mold body perimeter, allowing the spray pattern to adapt to different edge orientations and stripping edge alignments. This dynamic capability ensures consistent and reliable cleaning regardless of the specific geometric configuration, eliminating the speed variation problem inherent in linear spray bar movement
3Adaptability or versatility
If the entire carrier plate is sprayed, then cleaning is attempted, but only a small part of the jet falls on the critical edge section
Solution Approach 1:
The spray arrangement is designed to concentrate the medium delivery specifically at the edge section of the mold body, where fiber alignment and cleaning are most critical. By localizing the spray action rather than distributing it across the entire carrier plate, the system achieves high cleaning effectiveness at the edge while maintaining operational simplicity
4Manufacturing precision
If spray bar is used, then fiber alignment is attempted, but interior section fibers are resoftened and lumps come loose causing contamination
Solution Approach 1:
The spray arrangement is positioned and configured to deliver medium exclusively to the edge section of the mold body, keeping the interior section dry. This localized spraying prevents the medium from softening interior fibers or causing lumps to come loose, thereby eliminating contamination of the machine compartment while still achieving the desired edge section fiber alignment
