Senix Complete Mouse OEM Manufacturing Process – Customization from Molding to Shipping

For global buyers, brand owners, and distributors looking for a reliable mouse OEM factory and custom computer mouse manufacturing services, understanding the full production workflow is essential. A standardized, strict production process ensures stable product quality, customizable appearance and functions, on-time delivery, and lower after-sales risks.

As a professional mouse OEM/ODM factory with complete production lines, we strictly follow standardized manufacturing procedures covering mold opening, injection molding, SMT processing, automated painting, product assembly, and finished product shipping. Below is a detailed step-by-step introduction to our mouse OEM customization process, helping you fully grasp our production strength and quality control system.

1.Mouse OEM Tooling: Foundation of Customized Production

Mold opening is the first and core step of all customized mouse OEM orders, determining the mouse’s overall structure, appearance size, assembly accuracy and mass production stability. All customized wired mice, wireless mice, gaming mice and office mice need exclusive mold development according to customer design requirements.

Professional OEM Tooling workflow:

First, our engineering team conducts DFM manufacture ability analysis based on customers’ 3D drawings, 2D structural drawings and customization demands, optimizing unreasonable structural designs to avoid assembly failures and mass production defects. After confirming the design scheme and signing the formal cooperation contract, we start raw material preparation for molds, including high-quality mold steel and standard mold bases.

Subsequently, we complete precision processing procedures such as mold core milling, electrode processing, hole position calibration and mold fitting. After mold assembly, multiple trial mold tests are carried out to verify the tightness, structural matching and molding effect of the mold. We will adjust and polish the mold repeatedly according to the trial-produced sample effect until the size, radian, button gap and overall structure fully meet customer standards. After customer sample confirmation, the official mold is locked to prepare for batch injection molding production.

Our factory supports full-custom and semi-custom mouse mold opening, including unique appearance shapes, special button layouts, ergonomic structural designs, etc. All molds are independently owned and managed with long-term maintenance services to support repeated batch production for customers.

2.Injection Molding: Precision Molding of Mouse Shells

Injection molding is the process of mass-producing mouse shells, which directly affects the appearance texture, durability and hand feel of the mouse. Our mouse OEM factory is equipped with standard dust-free injection workshops and multi-specification precision injection molding machines, dedicated to producing high-qualified mouse upper shells, lower shells, button keys, scroll wheel shells and other plastic parts.

We adopt high-quality raw materials with wear resistance, fall resistance and environmental compliance (meeting CE, RoHS certification standards). Before production, plastic particles are dried and purified to eliminate moisture and impurities that may cause defective products. During the injection molding process, we strictly control injection temperature, pressure, speed and cooling time to ensure uniform shell thickness, no shrinkage, no bubbles, no burrs and no deformation.

After injection molding, professional staff conduct full appearance inspection and size screening. Unqualified products such as deformed shells and defective burrs are eliminated uniformly, and qualified plastic parts are sorted and stored in a dust-free and moisture-proof special area, waiting for subsequent surface treatment and assembly. For special customized mice, we support double-color injection molding and integrated molding processes to enrich product appearance and structural diversity.

3.SMT Processing: Core Electronic Assembly of Mouse PCBA

SMT patch processing is the key link to realize mouse functional performance, responsible for the precision mounting of core electronic components on the mouse PCB circuit board, which determines the mouse’s sensitivity, stability, signal transmission speed and service life.

Our OEM SMT production line adopts fully automatic high-speed patch equipment, with a standardized and efficient processing flow: First, apply uniform and precise solder paste on the PCB pad through a steel mesh; then mount precision components such as chips, sensors, resistors, capacitors and wireless modules on the designated positions of the circuit board through an automatic mounter; next, complete soldering through a reflow oven with constant temperature gradient control to ensure firm component welding and no virtual soldering or missing soldering.

After SMT processing, we conduct strict quality inspections to eliminate defective boards such as offset components and faulty welding. Then we complete program burning, function testing and aging tests of the mouse motherboard to ensure that the key functions such as cursor movement, key response, wireless connection and DPI adjustment are normal and stable. All PCBA boards meet industrial-grade quality standards, supporting long-term stable use of finished mice.

4.Automated Painting: Upgrade Mouse Appearance & Hand Feel

Automated painting is an indispensable personalized customization process for high-end OEM mice, which can optimize the mouse’s hand feel, appearance texture and wear resistance, while realizing customer-specified brand color matching and personalized effects. Our factory has a professional spraying workshop to avoid dust impurities affecting the surface effect.

According to customer customization requirements, we provide multiple spraying processes: matte oil spraying, glossy oil spraying, anti-slip oil spraying, soft-touch frosted spraying, etc. The whole process includes shell surface cleaning, electrostatic dust removal, primer spraying, constant temperature curing, topcoat spraying and secondary curing. Each link strictly controls the spraying thickness and uniformity to ensure no color difference, no paint peeling, no scratches on the mouse surface.

On the basis of oil spraying, we support extended personalized processes such as silk screen printing, laser engraving, brand logo printing and pattern customization, helping customers build exclusive brand mouse products. The sprayed finished shells have the characteristics of anti-fingerprint, anti-slip, wear-resistant and corrosion-resistant, effectively improving product grade and user experience.

5.Finished Product Assembly: Precision Matching & Functional Debugging

Assembly is the process of combining all mouse accessories into finished products, including plastic shells, PCBA, scroll wheels, keys, connecting wires, batteries, magnetic rings and other parts. We adopt a standardized assembly pipeline with strict division of labor and operation specifications to ensure assembly accuracy and production efficiency.

The formal assembly process is carried out in a clean workshop: first, fix the PCBA and internal accessories to ensure stable internal wiring and no loose parts; then assemble the upper and lower shells, calibrate the key and scroll wheel positions to ensure flexible pressing and smooth rotation; finally, complete the overall assembly and shaping of the mouse.

After assembly is completed, full-function testing is carried out one by one, including key sensitivity test, DPI switching test, wireless Bluetooth connection test, delay test, endurance test and appearance inspection. All unqualified products are reworked and repaired uniformly, and only fully qualified products can enter the packaging link. Strict assembly and testing standards effectively reduce the defective rate of finished products and ensure consistent product quality of batch orders.

6.Finished Product Inspection & Shipment: Safe Delivery for Global Orders

The final shipment link focuses on quality re-inspection, standardized packaging and safe logistics delivery, which is the final guarantee for the smooth delivery of OEM mouse orders to global customers.

First of all, our QC team conducts inspection in strict accordance with international trade standards, covering product appearance, function, size, packaging and other indicators. We support third-party inspections to meet the quality inspection requirements of different regional markets. After passing the inspection, the finished mice are packaged in customized neutral packaging or customer brand packaging (color boxes, cartons, gift boxes, etc.), with anti-pressure and anti-collision protection measures to avoid damage during transportation.

In terms of delivery, we provide complete export documents and support multiple logistics methods such as sea freight, air freight and express delivery. Before shipment, we complete product classification, carton marking, container loading and other work, and track the logistics status in real time. For bulk OEM orders, we support stable batch delivery and flexible delivery cycle arrangement to meet the procurement needs of global brand dealers and cross-border sellers.
