Project Overview

A cleaning, pretreatment, e-coating, and drying case for battery packs, battery boxes, vehicle body parts, and castings. This case is not a single-machine display. It is a production-oriented solution built around real factory needs. For manufacturers expanding capacity, serving overseas customers, improving delivery reliability, or upgrading workshop image, a surface treatment line, spray coating line, e-coating line, powder coating line, cleaning pretreatment line, or robotic painting cell should be planned together with product structure, process flow, plant layout, operators, safety, energy use, and long-term maintenance.

Yufeng starts this type of project by confirming product size, weight, material, target output, color quantity, coating standard, available workshop space, loading and unloading method, environmental requirements, and future expansion plan. Many buyers first compare machine price, but the real long-term cost is created by rework, changeover time, labor dependence, energy consumption, maintenance difficulty, and unstable quality. When these points are clarified before manufacturing, the production line becomes easier to accept, operate, and explain to global customers.

Customer Pain Points

Battery packs and body-related parts need high cleanliness, corrosion resistance, and process consistency. Unstable pretreatment can cause poor adhesion, pinholes, and corrosion risk. These issues may look small when production volume is low, but they become serious when a factory starts to accept batch orders or export projects. International buyers usually care about whether the workshop is organized, whether the process is visible, whether quality can be repeated, and whether the supplier can deliver on time. If the line layout is unclear, the sales team also has difficulty explaining where capacity and quality control come from.

Another pain point is that coating quality is hard to copy. Surface treatment depends on pretreatment stability, spray distance, spray angle, airflow, temperature, film thickness, hanging method, workpiece speed, and drying time. If these factors rely only on experienced workers, the factory will see quality variation when people change, orders increase, or products change. A good production line helps ordinary operators follow a repeatable standard instead of depending only on individual skill.

Yufeng Solution Design

Yufeng uses tank layout, spray cleaning, e-coating control, oven temperature control, and inspection points to stabilize corrosion-protection quality. The goal is not to force every customer into full automation. The right solution depends on current order volume, product variety, budget, and future upgrade needs. For some factories, the first stage is to standardize conveying, loading, unloading, coating, drying, and inspection. For higher-volume factories, the next stage can add robotic spraying, automatic recognition, barcode traceability, data records, energy monitoring, and MES connection.

In mechanical design, we focus on stable workpiece positioning, convenient operation, maintenance access, filter replacement, booth cleaning, oven service space, and safe abnormal-part handling. In line layout, we reduce crossing logistics and unnecessary handling so that workpieces move through a clear route. For large parts, we also pay attention to lifting safety, transfer space, aisle width, and the path for rework or offline inspection.

Key Processes Shown in the Photos

The photos show typical equipment and site layout, including loading and unloading areas, conveyor structures, spray or e-coating stations, curing and drying, cleaning pretreatment, powder coating booths, robotic spraying, and supporting devices. Real project images help buyers understand how the equipment serves production instead of only seeing isolated machines.

Each photo answers a practical manufacturing question: how the workpiece is positioned, how manual handling is reduced, how coating coverage is improved, how cleaning and drying become more reliable, and how the workshop becomes easier to manage. For cross-border purchasing, real case photos reduce communication cost and help buyers judge whether the supplier has complete project experience.

Suitable Applications

battery pack electrophoresis line planning, equipment upgrade, capacity improvement, and turnkey line discussion
vehicle body e-coating line planning, equipment upgrade, capacity improvement, and turnkey line discussion
pretreatment line planning, equipment upgrade, capacity improvement, and turnkey line discussion
cleaning and e-coating line planning, equipment upgrade, capacity improvement, and turnkey line discussion
anti-corrosion production line planning, equipment upgrade, capacity improvement, and turnkey line discussion

The solution is also suitable for manufacturers that want to improve factory presentation, reduce rework, reduce labor dependence, improve surface consistency, and build a standardized production process. The best configuration is different for each product, so Yufeng provides staged implementation advice based on product structure, takt requirement, investment budget, and workshop conditions.

Project Advantages

First, the workflow becomes clearer. A continuous line turns production from scattered manual movement into a visible process where managers can identify bottlenecks faster. Second, quality becomes more stable. Key process factors are controlled by equipment parameters, fixtures, and inspection points. Third, the workshop looks more professional. An organized line, clear stations, and real project photos help factory audits and buyer communication. Fourth, the system is easier to upgrade. Interfaces for recognition, data collection, robots, MES, and quality records can be reserved for future stages.

For export-oriented manufacturers, these advantages also support quotation and customer trust. Buyers do not only ask whether equipment can run. They also ask whether the supplier can deliver continuously, control quality, and respond quickly when problems occur. A well-planned production line gives the sales team stronger evidence when presenting factory capability.

Buying Advice

Before purchasing this type of line, customers should prepare drawings, sample photos, maximum dimensions, weight range, material, shift output, color quantity, coating standard, pretreatment requirement, workshop layout, environmental requirement, and target export market. If there is an old line, videos of the current process, common rework issues, energy data, and labor arrangement are also useful. Better input leads to a more accurate design.

Do not compare only booth size or total equipment price. It is more important to check whether the supplier understands product characteristics, model changeover, maintenance access, rework path, acceptance standard, and future expansion. A low-price line that does not fit the site can later become a higher cost in rework, downtime, and management difficulty.

Delivery and Support

To make the project practical, Yufeng provides process route planning, equipment layout, takt estimation, key station planning, maintenance space review, energy-use points, and acceptance criteria during the design stage. During manufacturing, project photos, videos, and progress records can help customers understand the build status. During delivery, operation training, wearing-part advice, maintenance points, and upgrade suggestions are provided.

These documents are not only for internal operation. They can also become factory-audit materials, purchasing communication materials, and project presentation assets. For manufacturers developing overseas customers, a visible, explainable, and maintainable production line is part of long-term competitiveness.

Project Summary

The core value of Battery Pack and Vehicle Body E-Coating Pretreatment Line Case is to turn scattered manual experience into a repeatable production process. Through proper conveying, spraying, e-coating, powder coating, cleaning, drying, inspection, and maintenance planning, customers can reduce rework, improve appearance consistency, reduce workshop disorder, and show more mature manufacturing capability to buyers.
