Si-TPV power tools handle material for improved ergonomics

describe:

When using Si-TPV the design and development of handles for powered and non-powered tools and handheld products, not just appears to simply enhance the aesthetically pleasing of a device, adding a contrasting color or texture. Especially, Si-TPV overmolding’s lightweight functionality also elevates ergonomics, deadens vibration, and improves a device’s grip and feel.

Power tools are highly adopted by industries such as construction, home improvement aerospace, automotive industry, shipbuilding, and energy. Homeowners also utilize them for various residential applications.

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.

    SILIKE developing a variety of Si-TPV elastomers is a versatile material that has the properties of both silicone rubber and thermoplastic elastomer, It is lightweight, durable, and resistant to wear and tear, making it an ideal choice for many applications. to serve sporting &leisure equipment, personal care, power &hand tools, lawn and garden tools, toys, eyewear, cosmetic packaging, healthcare devices, smart wearable devices, portable electronics, hand-held electronics, household, and other appliances markets, with a long-lasting comfortable soft touch feel, and stain resistance, these grades meet application-specific needs for aesthetics, safety, antimicrobial and grippy technologies, highly resistant to chemicals.
    However, Over-molding is a great solution, especially in power tools devices — is a product that's easy to use and withstands impact, abrasions, chemical reactions, and changes in temperature and humidity, it perfectly meets a critical need for the use of handheld. Plus, Over-molding allows manufacturers to create Ergonomically products that are both strong, durable, flexible, and lightweight. This process involves combining two or more materials to create a single, unified product. compared to traditional methods of joining two parts together. manufacturers are able to reduce costs associated with production and assembly. As well as, can be used to create products with unique shapes and designs.

    Si-TPV silicone-based thermoplastic elastomer material——Advanced TPU Grip Solutions: This is a new type of TPU Formulations for Enhanced Grip that gives knife handle designers a high degree of design freedom, including more color options, Soft Slip Coating Technology and visual appeal. The vermolded material can be injection molded or extruded, providing a long-lasting, skin-friendly feel without the need for secondary treatments, and without the risk of precipitation and sticking in the long term. Thanks to its elasticity, the handle can be used as a shock absorber and cushion to protect hands from injury when cutting hard objects. In addition, this material is characterized by excellent chemical resistance, corrosion resistance, hydrophobicity and dirt resistance, as well as good weathering, abrasion and scratch resistance, and is well adapted to the environment and has a suitable weight. It is ideal for soft touch overmoulding on handle grip.

Application

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...

Bond Requirements

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.
