SILIKE Si-TPVs Overmolding can adhere to other materials through injection molding. suitable for insert molding and or multiple material molding. Multiple material molding is otherwise known as Multi-shot injection molding, Two-Shot Molding, or 2K molding.
SI-TPVs have excellent adhesion to a variety of thermoplastics, from polypropylene and polyethylene to all kinds of engineering plastics.
When selecting an Si-TPV for an over-molding application, the substrate type should be considered. Not all Si-TPVs will bond to all types of substrates.
For more information regarding specific over-molding Si-TPVs and their corresponding substrate materials, please feel contact us.
Si-TPV soft over-molded material is an innovative way for manufacturers who produce hand and power tools, they need unique ergonomics as well as safety and durability, Main products applications include hand and power-tool grips handles such as cordless power tools, drills, hammer dills & impact drivers, dust extraction and collection, grinders, and metalworking, hammers, measuring and layout tools, oscillating multi-tools and saws...
In common with many products, power tool manufacturing companies are facing the challenge of designing tools to fit operators’ needs. Misuse of electrically powered portable tools can cause many fatal and painful injuries. With the development of cordless tools, the addition of battery elements in power tools has increased the tool’s weight. During the tool manipulation with the hand, such as pushing, pulling, twisting, etc., the user needs to apply a certain grasping force for safe manipulation. Mechanical loads are hereby directly transferred to the hand and its tissues, where each subject applies its preferred grip strength.
To overcome these design-related challenges manufacturers need to focus more on the ergonomic design and comfort of a user. Ergonomically designed power tools provide better comfort and control to the operator, allowing the work to be completed with ease and less fatigue. Such tools also prevent and reduce the health problems associated with or caused by using specific power tools. Besides, features such as vibration reduction and non-slip grips, balancing tools for heavier machines, lightweight housings, and extra handles help enhance user comfort and efficiency while using the power tools.
Since productivity and efficiency have been strongly linked to the level of comfort/discomfort, designers of power tools and products need to optimize human/product interaction in terms of comfort. This can be mainly done by increasing the functionality of the tools and products and also by the improved physical interaction between the product and the user. Physical interaction can be improved by the size and shape of the gripping surfaces and also the materials used, since it has been shown that a great correlation exists between the mechanical properties of the materials used and the subjective psychophysical response of the user, Some Results also suggest the handle material has a greater influence on the comfort rating than the handle size and shape.
