Custom Brush Handle Designed for a Perfect Fit
Precise Integration of Handle and Head Enhances Professionalism and Efficiency
To address common market issues such as loose connections and dimensional inaccuracies between brush handles and heads, the client sought a customized solution that would ensure stable assembly and consistent appearance. Leveraging years of experience in plastic injection molding, GH Plastics implemented high-precision dimensional control at the junction of the brush handle and head. This not only ensured a perfect fit during insertion but also maintained consistent tolerance during mass production, preventing quality instability.
Client Background
A professional manufacturer of dental cleaning tools specializing in interdental brushes, polishing brushes, and other dental consumables, with high standards for component quality, durability, and a stable supply chain.
The client in this case is a Taiwanese professional oral care product manufacturer, dedicated to the design and development of dental cleaning aids. Their products are primarily sold to dental clinics, medical channels, and overseas home care markets. Since the products come into direct contact with the oral cavity, the client has strict requirements for the structural strength, assembly precision, and user feel of the brush handles and heads. They sought a manufacturing partner capable of providing stable mass production and customized design to enhance product quality and strengthen brand competitiveness.
Customer Needs
The client aims to develop a specialized brush handle that achieves zero-tolerance fit with existing brush heads, preventing loosening or slipping during use. Additionally, the handle must feature ergonomic design to enhance user comfort, comply with food-grade plastic material standards, and ensure stable mass production.
To meet international market demands for consistent appearance and professional image, the client also prioritizes surface finishing and structural symmetry of the finished product. They seek to use custom molds to guarantee precision consistency and quality control during high-volume production.
Solution
GH Plastics conducted multiple development discussions with the client, focusing on key aspects such as brush handle angle and joint dimensions for customized design and mold optimization. Ultimately, they produced a dedicated brush handle that perfectly matches the client's product. This handle is made from food-grade PP material, featuring a sturdy structure and comfortable operation feel, and is suitable for automated production, significantly enhancing production stability.
Project Results
GH Plastics successfully developed a custom brush handle with zero-tolerance fit and strong structure, meeting the client’s requirements. Precision molding ensured consistent quality and reduced defects during mass production. The handle passed durability tests and was smoothly integrated into the client’s supply chain, receiving positive market feedback. This collaboration established Guang Hong Plastics as the client’s long-term injection molding partner.
