We specialize in custom-made precision injection molds for electronics, with applications ranging from connectors and lead frames to micro-gears and LCP antenna elements. Our production utilizes high-speed precision machining, mirror-finish EDM, and multi-cavity hot runner systems, combined with conformal cooling designs to ensure molding consistency and efficiency. Our comprehensive service covers everything from initial DFM reviews and rapid mold trials to full-dimensional inspection, and includes two rounds of free mold modifications. Key advantages include excellent filling balance across multiple cavities, superior mold fatigue life, and controllable lead times, effectively reducing overall manufacturing costs.
Our company is an integrated solution provider specializing in injection mold design and manufacturing as well as plastic injection molding. We are committed to offering end‑to‑end services—from product development, mold design, and tooling fabrication to production injection molding—for customers in the medical, consumer goods, automotive, home appliance, and electronics sectors.
As China Electronic Precision Injection Molds Manufacturers and Electronic Precision Injection Molds Suppliers, we maintain a comprehensive in‑house machining chain, equipped with high‑precision CNC machining centers, EDM (Electrical Discharge Machining), wire EDM (WEDM), precision grinders, CNC lathes, milling machines, deep‑hole drilling machines, and other mold‑making equipment. Our injection molding workshop houses more than 20 injection molding machines with various clamping‑force tonnages, covering a wide molding range from small precision components to medium‑ and large‑sized structural parts. These are complemented by auxiliary peripheral equipment such as mold temperature controllers, centralized material feeding systems, and automated robotic pick‑and‑place units. This robust infrastructure gives us the proven capability to design, develop, and manufacture medium‑ to high‑precision injection molds, as well as to undertake high‑volume production orders.
Backed by an experienced team of mold structure and process design engineers, we leverage the vertical integration advantage of integrated tooling and molding to significantly shorten the lead time from product development to mass production, while effectively reducing overall costs for our customers.
Upholding the philosophy of “Customer First, Continuous Improvement” Shanghai Pingzhou Plastic Products Co., Ltd. looks forward to providing partners across various industries with cost‑effective, rapidly responsive solutions for plastic products and injection molds.

READ MOREShanghai Pingzhou Plastic Products Co., Ltd. is a specialized manufacturer and supplier of electronic precision injection molds, based in Shanghai, China. With over 20 years of experience and a dedicated team of 60+ technicians, we provide end-to-end solutions from mold design and tooling fabrication to high-volume injection molding. Our molds serve the electronics, automotive, medical, and home appliance industries, delivering components with tight tolerances and reliable performance.
Our in-house facility spans 8,000 square meters and is equipped with high-precision CNC machining centers, EDM, wire EDM, precision grinders, and more than 20 injection molding machines. This vertical integration allows us to control quality at every step, reduce lead times, and offer cost-effective solutions for complex electronic components.
We offer a comprehensive range of electronic precision injection molds, each tailored to specific applications. Below is an overview of our standard offerings:
| Mold Type | Typical Applications | Key Materials | Key Features |
|---|---|---|---|
| Relay Housing Injection Molds | Automotive electronics, industrial controls, new energy | PPS, V-0 flame-retardant materials | Heat resistance up to 220°C, high insulation, 25-35s cycle |
| Micro-gear Injection Molds | Actuators, medical pumps, smart home devices | POM, PEEK | Self-lubricating, low friction, high wear resistance |
| Electronic Connectors Injection Molds | 5G base stations, Type-C, automotive ECUs | LCP, PA9T | Withstands 260°C reflow, V-0 rated, thin-wall capability |
| LED Display Frame Injection Molds | LED displays, lighting, signage | PC, PMMA | High optical clarity, dimensional stability, aesthetic finish |
Each mold type is engineered for specific operating conditions. For relay housings, we use high-temperature resistant materials like PPS to ensure performance in engine bays. Micro-gears benefit from self-lubricating POM or PEEK, reducing friction and noise. Connectors require LCP or PA9T to survive lead-free soldering. Our engineers select the optimal material based on your part's function, thermal environment, and regulatory requirements.
We also consider factors like electrical insulation, creep resistance, and flame retardancy. For example, many electronic components require V-0 rated materials to meet safety standards. We can customize colors and additives to match your specifications.
Precision is at the core of our molds. We achieve tolerances as tight as ±0.01mm on critical dimensions, ensuring consistent part quality. Our high-speed machining and mirror-finish EDM produce smooth surfaces and sharp edges, essential for thin-wall connectors and micro-gears. We use multi-cavity hot runner systems with conformal cooling to maintain filling balance and reduce cycle times.
Our injection molding workshop operates more than 20 machines with clamping forces ranging from 50 to 550 tons. This allows us to handle both small precision components and larger structural parts. We support production volumes from prototype runs to millions of parts annually. With automated robotic pick-and-place and centralized material feeding, we ensure consistent quality and efficient throughput.
We configure each mold based on your part design and production requirements. Options include:
Our molds are designed for easy integration with automated production lines, including robotic part removal and conveyor systems. We also offer two-color injection molds for complex assemblies, reducing secondary operations.
Quality is embedded in our process. We follow a three-level inspection system: first article, in-process, and final inspection. Our metrology lab is equipped with 2D and 3D coordinate measuring machines to verify dimensions and geometry. We conduct mold trials to validate part quality and process stability before mass production. All materials comply with RoHS and REACH requirements.
We provide full-dimensional inspection reports with each mold delivery. For production runs, we implement statistical process control to monitor key characteristics and ensure yield rates.
We design molds for easy maintenance, with accessible cooling channels and replaceable wear parts. We provide spare parts lists and recommend maintenance schedules to maximize mold life. Our after-sales team offers technical support and can perform mold refurbishment when needed. We also stock critical spare parts for quick replacement.
With each mold, we supply comprehensive documentation including design drawings, material certificates, and maintenance manuals. For production projects, we provide process parameters and quality control plans. We also offer training for your operators on mold handling and basic troubleshooting.
To prepare an accurate proposal, we need the following details:
With this information, our engineers perform a DFM analysis to identify potential issues and propose the most efficient mold design. We then provide a detailed quotation with mold specifications, lead time, and production costs.
We routinely hold tolerances of ±0.01mm on critical dimensions. For micro-features, we can achieve even tighter tolerances with advanced machining and process control.
Yes, our multi-cavity molds and automated production lines are designed for high-volume manufacturing. We can produce millions of parts per year with consistent quality.
For connectors that undergo reflow soldering, we recommend LCP or PA9T due to their high heat resistance and dimensional stability. We can also work with other engineering plastics based on your requirements.
Yes, we conduct mold trials to validate part quality and process parameters. We provide samples for your approval before starting mass production.
We use a combination of in-process inspections, SPC, and final dimensional checks. Our quality system is ISO-compliant, and we provide full inspection reports with each shipment.
Lead time depends on complexity. For standard precision molds, it is typically 4-6 weeks. We work with you to meet your project schedule.
Our portfolio also includes Relay Housing Injection Molds, Micro-gear Injection Molds, OEM/ODM Electronic Connectors Injection Molds Factory for applications with different operating ranges, interfaces or integration requirements.
