Solution Overview
Problem
The existing manufacturing processes for silicone gloves require multiple spraying steps, leading to high material consumption, complex operations, and increased costs, with issues in uniform coverage of silicon slurry in finger gaps and tiger mouth areas.
Innovation Solution
A manufacturing process that involves spraying liquid silicon on a glove blank once, with axial rotation and horizontal movement, using strategically positioned spraying ports and compressed air blowing to ensure uniform coverage, followed by controlled drying and cooling steps to maintain quality and reduce material waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple spraying steps are used to coat silicon slurry on glove mold, then the coverage uniformity is improved, but the manufacturing complexity and material consumption increase
Solution Approach 1:
The spray system is segmented into multiple independent spray nozzles positioned at different locations (front, rear, left, right) to target specific areas of the glove mold. Each nozzle can be independently controlled to spray silicon slurry at optimized angles and positions, achieving uniform coverage without requiring multiple complete spraying cycles.
Solution Approach 2:
The spray nozzles are arranged in three-dimensional space around the glove mold, utilizing spatial dimensionality to achieve comprehensive coverage. By positioning nozzles at different heights, angles, and locations, the system covers all surfaces including finger gaps and tiger mouth areas in a single integrated spraying operation.
2Manufacturing precision
If multiple spraying steps are adopted, then the silicon slurry coverage is improved, but the material consumption and cost increase
Solution Approach 1:
The spray nozzles are pre-positioned and pre-adjusted to optimal angles and locations before the spraying operation begins. The system is configured in advance to cover all necessary areas (finger gaps, tiger mouth, palm, fingers) with minimal overlap and waste, ensuring that silicon slurry is applied efficiently in a single pass without requiring corrective re-spraying.
Solution Approach 2:
Different spray nozzles are directed at specific regions of the glove mold where silicon slurry coverage is most needed (finger gaps, tiger mouth areas, palm). The system applies material locally and selectively rather than uniformly across the entire mold, reducing overall material consumption while ensuring adequate coverage of critical areas.
3Manufacturing precision
If complex multiple spraying process is used, then the coverage quality is improved, but the production time increases
Solution Approach 1:
Multiple spray nozzles that would traditionally operate in separate sequential steps are merged into a single integrated spraying system. All nozzles operate simultaneously during one spraying cycle, combining the functions of multiple steps into one coordinated operation, thereby maintaining high coverage quality while significantly reducing total process time.
Solution Approach 2:
The spraying system operates continuously in a single pass, with all spray nozzles functioning simultaneously throughout the spraying cycle. The glove mold moves through the spray zone in one continuous motion, receiving uniform coverage from all nozzles without interruption or repeated cycles, maximizing production efficiency while maintaining coverage quality.

AI summary
The present disclosure relates to a manufacturing process of a silicone glove, and belongs to the technical field of glove processing. The manufacturing process of the silicon glove is characterized in that the silicon glove is divided into a liner, a glove blank and a silicon layer from the inside to the outside, and liquid silicon is sprayed on a surface of the glove blank for once; when spraying the liquid silicon, the glove blank also rotates around its axis while horizontally moving on an assembly line; during spraying, a liquid silicon outflow channel at least includes a finger gap spraying port and a tiger mouth spraying port that are arranged fixedly; an arranging length of the finger gap spraying port is greater than or equal to a length of a finger area of the glove blank; an arranging length of the tiger mouth spraying port is greater than or equal to a length of a tiger mouth area of the glove blank; and the purpose of covering a silicon slurry on the surface of the glove blank through once spraying may be implemented, and the uniform covering of the silicon slurry in the finger gaps and the tiger mouth of the glove blank is ensured, thereby saving the sizing material consumption and reducing cost.
