Custom ESD R-KLT Plastic Containers Manufacturers

Reinforced Anti-Static Containers for Circulation Logistics

Suzhou He Cheng Feng Esd Circulation Box Co., Ltd. has supplied standardized plastic logistics containers since 2013. As a China-based manufacturer and supplier of returnable ESD packaging, we build the Custom ESD R-KLT Plastic Containers range as the reinforced branch of our ESD KLT Container family. The complete returnable programme is available under our Products section.

The R-KLT series is specified when a small load carrier must combine permanent anti-static protection with heavy-duty mechanical performance. Strengthened sidewalls, a reinforced base and stable stacking geometry keep automotive parts, electronic components and semiconductor materials in the same protective package through production, storage and transport.

Product Range and Positioning

The current ESD R-KLT range contains six standard models, each positioned for a specific handling duty. We select the model according to part weight, circulation route, storage equipment and exposure to oil or moisture.

The 31xx and 41xx models cover workshop, tote and rib-reinforced duties; the 61xx models add heavier, stackable and oil-resistant capacity. All six models share the same ESD material behavior, so the complete circulation pool can be standardized.

Where the R-KLT Series Fits

• Automotive component logistics: ECUs, sensors, connectors and precision metal parts moving between suppliers and assembly lines.
• Electronics and semiconductor workshops: PCBs, chips and precision modules that require ESD-controlled handling.
• Mechanical engineering and hardware: fasteners, cutting tools and machined components that need impact-resistant totes.
• Warehouse and line feeding: stackable containers for order picking, kitting and automated storage and retrieval areas.

A parallel series, the ESD RL-KLT Container, is available when label-holder or turnover-box features are required in the same ESD KLT family.

ESD Protection Is Part of the Molding

Our ESD products are molded with anti-static compounds, so the protection does not depend on a surface coating that can wear off through handling and washing. This gives more predictable performance in returnable logistics, where containers are reused for many trips.

For electronic applications, industrial anti-static standards are the acceptance benchmark. We confirm the ESD behavior of each container family against those standards during project qualification.

Reinforced Structure, Stacking and Automated Flow

Strengthened sidewalls and base construction are the defining characteristics of the R-KLT line. They provide a higher load margin for dense parts and reduce body deformation in racks, pallets and floor stacks. Rib-reinforced models such as ESD-R-KLT4129 add stiffness where dimensional stability is critical.

Stacking stability is engineered into the top and base geometry. Containers align evenly, which protects the contents and makes handling predictable. The series is designed to be compatible with automated material flow systems; we confirm the base footprint, clearances and stack orientation against the conveyor, AGV or storage interface before finalizing the configuration.

Customization and Mold Development

Suzhou He Cheng Feng Esd Circulation Box Co., Ltd. supports one-stop product customization and custom mold development. For volume programs, we can adapt dimensions, stacking details and internal molded features to the component family and the customer storage system.

Color, molded logos and label areas can be settled during tooling development. The goal is to keep the R-KLT container standardized enough to circulate in the supply chain, while matching the specific part geometry and handling method.

Quality Assurance and Acceptance

Production follows rigorous standards, and all products are checked to comply with industrial specifications. For ESD containers, acceptance covers dimensional conformity, stacking alignment, structural integrity and anti-static behavior.

For a new project, we confirm the acceptance sample, documentation and inspection points before serial supply. After-sales support and technical service remain available once the containers enter circulation.

Information We Use to Configure Your Solution

To prepare a configuration and quotation, we need the operating parameters that define the container. Our technical and sales teams use this data to select a standard model or propose a custom mold.

• External or internal working dimensions, footprint and usable volume required by the rack or line.
• Part type, unit weight and quantity per container.
• ESD sensitivity and the controlled area where the containers will be handled.
• Stacking height on racks, pallets or floor stacks.
• Handling method: manual, roller conveyor, AGV, automated storage or line-side delivery.
• Exposure to oil, moisture, temperature or wash cycles.
• Requirement for lids, label holders, dividers or barcode areas.
• Applicable customer, VDA or plant-specific logistics specifications.
