Precision plastic components for optical communication refer to plastic parts used in communication equipment. Precision injection molding technology is widely adopted for mass production of small, complex and intricate plastic components, which typically require high precision, high strength and excellent surface quality. Such precision molded plastic parts are extensively applied in equipment for fiber optic communication systems, fiber access networks, fiber-optic data transmission, and other IoT (Internet of Things) connectivity scenarios.

Using precision molds and advanced injection molding technology, complex parts with very small dimensional tolerances can be manufactured, with common tolerances reaching ±0.02mm or even less.

As 3C electronic products continue to develop towards smaller and lighter designs, precision injection-molded parts often need to be miniaturized and have higher integration during design, such as integrating multiple functions into a single component.

The materials for injection-molded parts typically need to meet performance requirements such as impact resistance, drop resistance, and high-temperature resistance, especially for the shells and internal components of smartphones and tablets, where higher strength and durability are required.
The DFM stage ensures that product design aligns with manufacturing processes. The design team conducts in-depth analysis of product geometry, dimensions, and surface requirements, assessing manufacturability. At the same time, suitable injection molding materials are selected, and product design is optimized to meet injection molding processes. The goal of this stage is to ensure that the product meets functional requirements while being efficient and cost-effective to manufacture.
During the mold design stage, the team uses CAD/CAM software to create 3D models and design the various components of the mold in detail. Considerations include material selection, cooling systems, ejection mechanisms, etc., to ensure the mold meets production requirements. After outputting the drawings, precise guidance is provided for mold manufacturing, ensuring mold quality and performance.
In the mold manufacturing stage, raw materials are prepared, rough machining, and finish machining are carried out based on the design drawings. Processes such as electrical discharge machining (EDM) and wire cutting are used to handle complex features. Subsequently, surface treatment is performed to improve mold hardness and wear resistance. Finally, the mold components are assembled to ensure smooth operation of the mold, preparing it for mold testing and mass production.
During the mold testing stage, the mold is installed on the injection molding machine for initial injection testing. Based on the test results, adjustments are made to the mold and injection molding process parameters to optimize product quality. The mold-tested products are thoroughly inspected to ensure they meet design requirements. Successful mold testing is a key indicator of mold qualification and the selection of the optimal molding process.
In the mass production stage, a production plan is developed based on market demand, and injection molding materials and auxiliary equipment are prepared. Mass production is carried out according to the production plan and injection molding process parameters to ensure stable product quality. Continuous quality control is implemented, with strict inspection of products during the production process. Finally, qualified products are packaged and delivered to meet customer needs.
Precision injection molded plastic parts for fiber patch cords are widely used in communications, electronics and other industries, requiring injection molding processes with high precision, complexity and mechanical strength. With high-quality mold design, precision injection molding, stringent quality control and optimized post-processing procedures, high-performance precision molded components for equipment housings can be manufactured to meet the requirements of various high-precision mechanical parts.
Precision components made of special plastic materials are widely adopted in electronics, optical communications and other industries. Featuring outstanding mechanical properties, heat resistance, electrical performance and corrosion resistance, they serve as an ideal option for manufacturing high-precision, high-performance industrial components. Accurate injection molding and post-processing technologies enable the production of high-quality parts that satisfy strict quality standards and dimensional tolerances.
Typically, we require 2D and 3D drawings to provide an accurate mold quotation and manufacturing. Supported 2D drawing formats include: AI, PDF, DWG, CAD, DXF, DLG, etc.; supported 3D drawing formats include: STP, IGS, etc.
Our company designs molds based on product drawings, but we do not design products. If customers do not provide product design drawings or physical samples, we cannot proceed with processing.
Our annual mold capacity is 300 sets. We have multiple professional mold designers and experienced technicians. Our team consists of over 130 personnel, and we have over 180 imported advanced mold manufacturing equipment.
Yize Mould manufactures strictly according to the drawing accuracy provided by the customer and communicates with the customer regarding the mold's purpose and accuracy requirements. If the mold does not meet the customer's requirements due to our manufacturing issue, we will arrange for rework. If the product is scrapped due to errors in the customer's drawings, it will be discussed separately.
