Customized Acoustic & Wearable Injection Molds Design
In the consumer electronics manufacturing sector, Acoustic & Wearable Injection Molds provides core tooling equipment for the mass production of various small audio and wearable electronic products. Leveraging high-precision customized injection molds, it can stably produce a full range of acoustic and wearable plastic components, including TWS Bluetooth earphone housings, acoustic chambers for headphones, dual-color smartwatch straps, soft rubber wristbands for fitness trackers, and portable Bluetooth speaker shells.
KRMOLD specializes in customized R&D for Acoustic & Wearable Injection Molds, providing comprehensive support for clients in the product launch markets for smartwatches, fitness trackers, wearable motion sensors, wireless Bluetooth earphones, small portable audio devices, and various micro-personal electronic products.
Before each Acoustic & Wearable Injection Mold is officially molded, engineers conduct a multi-dimensional professional assessment of the mold's molding capabilities. This includes adapting the mold cavity structure to the complex, irregular geometry of the product; selecting specialized injection molding materials suitable for human contact and acoustic conduction; developing a mold surface release treatment plan tailored to the low-sensitivity requirements of wearable products; refining the micron-level tolerance standards for the mold cavity; and simulating tens of thousands of continuous injection cycles to verify the dimensional stability and appearance consistency of the entire mold in long-term mass production. This approach aims to prevent issues such as warpage, dimensional deviations, and appearance defects from the mold's origin.
Advantages of Acoustic & Wearable Injection Molds
1
Adapted for Flexible Molding of Liquid Silicone (LSR)
KRMOLD has developed a dedicated LSR Acoustic & Wearable Injection Molds that can mold a bio-mimetic, skin-like surface, a honeycomb cushioning micro/nano structure, micron-level suction cups, and a flexible hinge structure combining thin-walled liquid silicone with shape memory alloy in a single step.
The entire LSR Acoustic & Wearable Injection Molds is designed to balance lightweight molding with high tensile strength of the finished product. Precise material and temperature control through the Acoustic & Wearable Injection Molds significantly improves the comfort of wearable products during extended wear, making it a core injection mold carrier for the mass production of soft silicone wearable accessories.

Multi-material Dual-color Integrated Injection Molding
KRMOLD has created an integrated injection mold suitable for multi-material co-injection and two-color molding. These composite Acoustic & Wearable Injection Molds enable simultaneous co-injection molding of an inner layer of hard engineering plastic and an outer layer of soft silicone. Products such as integrated rubber coating of smartwatch cases and straps, and waterproof soft rubber rings for earphone shells, can all be completely molded using a single two-color injection mold.
Utilizing the independent flow channel and sealed parting structure design within the Acoustic & Wearable Injection Molds, the finished product can easily meet high waterproof sealing standards of IPX4~IPX7 and even IP68. A single multi-functional injection mold simultaneously meets multiple requirements for product structural strength, wearing comfort, and aesthetic texture.

Micro-precision Micro-injection Molding
This series of Acoustic & Wearable Injection Molds can reliably complete the high-precision molding of 0.05mm ultra-thin-walled plastic parts and micron-level sound guiding holes in Bluetooth earphones.
Relying on the ultra-high fitting precision of the injection mold cavity, it achieves precise encapsulation of various wearable sensor shells such as heart rate and motion sensors, eliminating issues such as overflow, material shortage, and dimensional deviation, ensuring the consistency of batch molding of micro-acoustic cavities and sensor shells.
