The sales team plays an important role in confirming customer orders. They verify all details related to the order, such as product type, quantity, and delivery schedule. This step ensures that the customer’s requirements are met without errors.
Customers often request specific customizations in photocell lighting sensor products. These custom requirements are documented and reviewed by the technical team to ensure feasibility.
Contract Review Process
Once the order is confirmed, the contract review process begins. The engineering department evaluates the technical aspects of the order. They check whether the requested specifications align with production capabilities.
The finance department reviews pricing and payment terms. The quality control team ensures compliance with industry standards. A well-structured contract review process prevents misunderstandings and production delays.
Preparing Shipment Instructions and Purchase Orders
Inventory Checks and Planning
Before production begins, the warehouse team performs a detailed inventory check. This step confirms the availability of raw materials and components required for outdoor photocell light sensor manufacturing.
A sales plan order is then created based on material availability. If raw materials are insufficient, the procurement team initiates the purchasing process.
Material Procurement and Inspection
The procurement team sources high-quality materials from approved suppliers. They follow strict guidelines to ensure compatibility with Longjion’s production standards.
Upon arrival, the materials go through an IQC (Incoming Quality Control) inspection. This includes checking for material defects, verifying supplier compliance, and ensuring proper labeling. Only materials that meet the quality requirements proceed to production.
Production Preparation and Process
Equipment Inspection and Preparation
The engineering department inspects all machinery and production tools before starting production. Any malfunctions or maintenance needs are addressed to avoid disruptions.
Operation guidance documents are provided to production staff to ensure smooth operations. Training sessions are conducted to familiarize workers with updated manufacturing protocols.


Work Order Processing
The production department receives work orders based on the sales plan. A first article inspection (FAI) is conducted to verify the quality of the initial product. This helps identify any issues early in the production cycle.
If the first article inspection is successful, full-scale production begins. If any issues arise, corrective measures are taken immediately.
Planned Production and Quality Checks
Every stage of production undergoes thorough inspections. Quality control checkpoints are established to ensure that the light photocell sensor products meet the required standards.
Strict monitoring of the production line ensures consistency in assembly, performance, and appearance. The inspection team checks for electrical efficiency, weather resistance, and operational accuracy.
Finished Product Inspection and Shipping
Final Quality Inspection
Once production is completed, the finished products undergo final inspections. These inspections ensure that all products meet technical specifications and customer requirements.
Tests include:
- Functional testing of the photocontrol
- Durability tests under extreme environmental conditions.
- Electrical safety evaluations to ensure compliance with industry standards.
Shipment Preparation and Delivery
After the products pass the final inspection, they are packaged securely to prevent damage during transportation.
The logistics team prepares shipping documents and arranges transportation based on customer locations. The tracking system ensures customers can monitor their shipments in real-time.
Efficient shipping processes help Longjion maintain its reputation for timely deliveries.
Customer Returns and Order Management
Handling Returns
If a customer reports an issue, the sales team handles the return process. Returned products are inspected to identify defects or issues. Based on the findings, corrective actions are taken, such as replacement or repair.
Order Modifications and Cancellations
Customers may request modifications or cancellations before production begins. The company follows a streamlined process to accommodate such requests. Custom orders are carefully managed to ensure client satisfaction.
Summing Up
Longjion’s light controller production process is comprehensive and efficient. Each step, from sales order receipt to final delivery, is carefully managed. Strict quality control ensures the reliability of products like the photocell street light and dusk-to-dawn photocell sensor devices.
Effective schedule management and stringent inspections help in delivering top-quality products. This commitment enhances customer satisfaction and strengthens Longjion’s position in the market.
