Plastic Injection Hearing Aid Moulding

Plastic injection molding of hearing aids is a plastic processing technique in which molten plastic material is injected into a precisely designed cavity of a hearing aid mold under high pressure. After the plastic cools and solidifies, the mold is opened to remove the hearing aid components. Through this process, plastic components of hearing aids can be produced that have the exact same shape as the mold cavity.

P&M Plastic Injection Hearing Aid Moulding Introduction

Core Features：

High precision: Hearing aids are compact in size and have complex internal structures, requiring extremely high dimensional accuracy of components. Plastic injection molding can precisely control the size and shape of products, meeting the high-precision requirements of hearing aid components, such as controlling the dimensional tolerances of components within a very small range.

Complex structure forming ability: It can manufacture hearing aid components with complex geometric shapes, such as shells that conform to the shape of the human ear canal and fine acoustic structures inside, which are difficult to achieve with other forming processes.

High production efficiency: suitable for large-scale production, able to produce a large number of hearing aid components in a short period of time through automated operations, reducing production costs.

Wide material adaptability: Multiple types of plastic materials can be used, such as polypropylene (PP), polyoxymethylene (POM), ABS resin, etc. Different materials have different properties, which can meet the requirements of hearing aid components in terms of strength, toughness, corrosion resistance, acoustic performance, etc.

Good surface quality: The molded parts have a smooth surface, which can reduce subsequent processing steps and also help improve the comfort and appearance quality of hearing aids.

Production process：

Raw material preparation: Select plastic materials suitable for the performance requirements of hearing aid components, and dry them to remove moisture and other volatile substances from the materials, preventing bubbles and defects during the molding process.

Melting: Dry plastic particles are fed into the barrel of the injection molding machine through a hopper, and are melted into a molten state by heating the barrel and rotating the screw.

Injection: When the plastic melt reaches the predetermined temperature and pressure, the screw or plunger of the injection molding machine injects the molten plastic into the closed mold cavity at high or low speed through the nozzle.

Pressure holding: After filling the mold cavity with plastic, continue to maintain a certain pressure to compact the melt, increase plastic density, ensure that the plastic fully fills all corners of the mold, and reduce product shrinkage and deformation.

Cooling: After the pressure holding stage, keep the mold closed and allow the plastic to cool and solidify in the mold until it becomes hard enough to remove the product. The cooling time depends on factors such as the type of plastic, the size and thickness of the components.

Mold opening and removal: After the plastic product cools and solidifies, the mold is opened and the hearing aid components are removed from the mold using an automatic robotic arm or other manual tools.

Follow up processing: Remove possible sprues and burrs on the product, inspect the size, appearance, and performance of the product to ensure it meets quality requirements. As needed, some post-processing may also be performed, such as surface treatment, printing, etc.

P&M Plastic Injection Hearing Aid Moulding Feature And Application

Hearing aid housings: The housings of various types of hearing aids, including in the ear (ITE), in the ear (ITC), and behind the ear (BTE), can be manufactured through plastic injection molding to provide a comfortable wearing experience and good protective performance.

Internal components, such as the adjustment knob, battery compartment, and acoustic cavity of the hearing aid, can also be produced using plastic injection molding technology. These components play an important role in the functionality and convenience of the hearing aid.

Customized accessories: With the increasing demand for personalization, plastic injection molding can produce customized hearing aid accessories based on the patient's ear canal shape and other personalized features, improving the comfort and acoustic effect of wearing.
