TPU Injection Molding for Electronic Products - The Ideal Solution for Flexibility, High Elasticity and Precision Protection
As electronic products become increasingly thin, light, intelligent and multifunctional, the choice of materials and manufacturing methods for structural components is particularly important. TPU injection molded electronic products have become the preferred solution for many electronic product housings, protective covers, cushions and connecting parts. With more than ten years of experience in injection molding and advanced TPU material injection molding process, our factory is able to provide high-precision and customized TPU injection molded electronic products services to customers worldwide.
Product Description
Injection molding TPU parts is through the thermoplastic polyurethane (Thermoplastic Polyurethane) raw material melted at high temperature and then injected into a high-precision mold molding, cooling and shaping for the formation of electronic products, structural or functional parts. TPU material is a combination of rubber elasticity and plastic processing performance of the high-performance polymers, its natural flexibility and strength. TPU material is a high-performance polymer with both rubber elasticity and plastic processing properties, and its natural flexibility and high strength give it great design freedom.
TPU injection molded parts are widely used in electronic products, including but not limited to:
1. Drop-proof shells for cell phones and tablet PCs
2. Wearable devices (such as bracelets, headphones) flexible structural parts
3. Power cable sheaths and protective sleeves
4. Battery connector seals
5. Functional parts such as buttons, buffer rings, dust caps, etc.
We can provide customized TPU injection molding electronic product services according to customers' drawings or samples, supporting a variety of complex processes such as two-color injection molding, insert injection molding, overmolding injection molding, etc., to satisfy the multiple requirements of high-end electronic products in terms of structure, appearance, and function.
The product advantage features
Flexible and bend-resistant
TPU material is naturally soft and extremely resilient, and is not easy to break even after repeated bending over a long period of time, which is suitable for dynamic use environments.
High strength tear
Tear strength is much higher than traditional TPE or silicone materials, suitable for use in the need for wear-resistant, impact-resistant external structure of electronic products.
Excellent oil, water and weather resistance
After injection molding, the product has excellent sealing and chemical resistance, suitable for outdoor and humid environment in the application of electronic products.
High process flexibility
Can realize precision insert injection molding, soft and hard combination design, two-color injection molding, etc., to meet the needs of complex product design.
Rich surface texture
Surface can be realized glossy, frosted, leather, rubber paint and other treatments, to enhance product aesthetics and user experience.
Environmentally friendly and recyclable
TPU material is non-toxic and environmentally friendly, recyclable, and complies with RoHS, REACH and other international environmental standards.
Production Process
We have the professional ability of the whole process from mold design to finished product shipment, to ensure that each TPU injection molded parts meets the customer's design and functional requirements:
Drawing Evaluation and DFM Analysis
The customer submits 3D/2D drawings, and our engineers carry out the manufacturability analysis (DFM), optimize the structure, and make suggestions to facilitate injection molding.
Mold Design and Manufacturing
Adopt high precision mold steel, use CNC, EDM and other equipment for mold processing, and carry out T0, T1 trial mold verification during the mold development process.
Material Selection and Inspection
We select TPU raw materials of famous brands (e.g. BASF from Germany, Lubrizol from USA, etc.), and carry out incoming material performance testing and environmental protection certification.
Injection processing
Adopt fully automatic injection molding machine for molding control, equipped with precision mold temperature control, vacuum degassing, cooling system, to ensure stable quality of finished products.
Surface treatment and secondary processing
According to the needs of oil spraying, silk screen printing, laser engraving, adhesive coating and other secondary processing, to enhance the appearance and function of the product.
Quality Inspection
The whole process is equipped with QC nodes, and the finished products undergo a number of quality inspections such as appearance, size, function, tension, wear resistance, and aging test.
Packing & Shipping
We use protective packaging such as dust bag, blister tray, foam, etc. to avoid product deformation and scratch during transportation.
