The story behind an advanced mouse

The mouse with soft touch, good man-machine engineering performance and low friction is very popular in the market. A multinational commercial equipment manufacturer developed this kind of mouse with the design of modern new polymer materials. The product received good response when it was put into the market.

A computer mouse with soft hand feel and good mechanical properties will be preferred by the users. With the help of new polymer materials, an overseas corporation has manufactured a computer mouse that achieved US$400,000 in sales within a year.

A multinational manufacturer of commercial equipment has decided to develop an advanced line of computer mouse products that require good ergonomic performance and soft touch.

The business goal is to expand this market by developing a new high-performance mouse that is more comfortable and can enhance the user experience.

The design requirements

The key to product development is the soft touch of the mouse handle to give users a smooth feeling, easy to operate, and a very high physiological comfort.

In addition, some more traditional features are included in the design, such as four small legs on the underside of the mouse to reduce friction and easy to slide during operation.

Manufacturers look for high-performance materials solutions to achieve these features and significantly enhance the computer user experience.

The design team thought it needed a soft, chemical-resistant, color-stable material to make mouse handles.

In addition, they needed materials with low wear and friction to make mouse pins.

Break down the difficult points one by one

In light of the early success of the project, the OEM design team turned to privan because the company has a wide range of materials, from specialty polymers to thermoplastic elastomers (TPE).

The company's team works with manufacturers to meet specific performance requirements, and develops customized solutions with soft touch, good man-machine engineering performance and low friction.

In order to achieve the goal of mouse handle set by the manufacturer, a transparent TPE composite injection material GLS Versaflex was designed, which has good man-machine engineering performance, comfortable touch, excellent chemical resistance and good bonding performance with ABS substrate.

The technical support team of privan GLS has conducted extensive compatibility tests to prove that the material can be composite injected onto hard substrate and has good adhesion properties.

The customized Versaflex brand shor A has A hardness of 60 degrees and excellent tear strength.

This material has excellent chemical resistance to common substances (such as cosmetics and detergents) and foods (such as olive oil and mustard), and is easy to be injected into both components.

Two-component injection molding is an efficient manufacturing process, eliminating the time-consuming and costly assembly process.

For the mouse foot, puliwan designed a special type of LubriOne, that is, filled with acetaldehyde, which improves performance compared to pure acetaldehyde in the traditional design.

The material has excellent surface engineering properties such as low wear, low friction, high lubrication and no squeaking.

The mix mix developed by the team of puliwan company can make use of existing molds to avoid increasing the cost of molds.

The dynamic friction coefficient of LubriOne is 0.108, which is about 50% lower than traditional materials.

Therefore, compared with the existing model, the mouse's sliding ability is greatly improved, which is beneficial to enhance the user's experience.

The team is involved in all molding trials to help achieve proper component performance and works closely with OEM in global sales coordination, engineering and technical support.
