As Custom Automotive ESD RL-KLT Logistics Containers Manufacturers, we supply reinforced ESD-safe KLT containers for automotive parts flow, electronics handling and returnable logistics programs. This series combines reinforced walls and base, conductive material and dimensional stability so the same container can move through assembly line, warehouse and supplier return loops.
Based in Suzhou, China, Suzhou He Cheng Feng ESD Circulation Box Co., Ltd. was founded in 2013 as a professional manufacturer of standardized plastic logistics containers. We produce ESD and conductive circulation boxes, EU/HP standard containers, plastic pallets and matching accessories, and support custom mold development for special storage and transit requirements.
Our position in the ESD KLT product family
The ESD RL-KLT range is our reinforced turnover container line inside the ESD KLT Container family, alongside R-KLT, C-KLT, M-KLT and matching lids. While standard KLT designs focus on modular stacking, the RL-KLT structure adds mechanical strength without losing the stacking and nesting behavior needed for efficient circulation.
We manufacture the complete series under one roof, which lets us keep the material grade, molding process and dimensional control consistent from first article to serial production. The same tooling platform also allows practical modifications such as dividers, label holders or lid compatibility.
ESD RL-KLT range overview
Our current RL-KLT program covers the following seven standard models. Model numbers indicate the loading footprint series and each model has a defined application focus.
| Model | Positioning | Typical application |
|---|---|---|
| ESD-RL-KLT3047 | Stackable ESD-safe turnover box | Compact storage, transit and small-part handling |
| ESD-RL-KLT4047 | Antistatic turnover box with label holder | Line-side identification, labels and barcode placement |
| ESD-RL-KLT4013 | Antistatic KLT for automotive components | Sorting and protection of small automotive parts |
| ESD-RL-KLT4080 | Production line material handling box | Assembly feeding, kitting and work-in-progress transport |
| ESD-RL-KLT6047 | Warehouse stacking container | High-stack storage and distribution loops |
| ESD-RL-KLT6013 | Impact-resistant heavy-duty reinforced box | Heavy or impact-exposed part handling |
| ESD-RL-KLT6080 | Thickened storage box | Bulk automotive parts storage and inter-plant supply |
Engineering and material design
All RL-KLT models share a common design platform:
- Conductive ESD-safe material: controls electrostatic charge generation and supports static drainage in ESD-protected zones.
- Reinforced walls and base: carry stacking loads and withstand the knocks of daily handling.
- High dimensional accuracy: keeps the outside envelope stable for conveyors, robot grippers and automated storage systems.
- Stable stacking and nesting: full boxes stack cleanly, while empty units nest to reduce return transport volume.
Where the RL-KLT range fits
In automotive supply chains, these containers handle stamped parts, sensors, connectors, fasteners and small assemblies between tier suppliers, assembly plants and distribution centers. The 4013 and 6080 models suit component storage and transport; the 4080 and 4047 models are practical on assembly and kitting lines; the 6047 and 3047 models cover warehouse stacking and distribution loops.
For electronics and precision component projects, the same series protects PCBs, chips and sensitive devices from electrostatic discharge while keeping parts organized in ESD-controlled environments. The ESD R-KLT Container range remains an option when a lighter standard KLT format is acceptable.
Configuration, controls and automation integration
Automated lines rely on consistent outside dimensions, stack height, underlip geometry and grip surfaces. When you specify the interface, we confirm the RL-KLT model or tooling layout against those parameters. The proposal states the envelope, stacking height and load assumptions used for the configuration.
Customization can start from a standard model or from a new mold. Typical modifications include internal dividers, label holder positions, lid compatibility, colors and part-specific inserts. Our ESD KLT Container Lid range includes sealed and VDA-standard options.
Quality approach and lifecycle support
Our ESD products meet industrial anti-static standards for electronic and precision-component packaging. Production follows rigorous standards, and our technical group reviews material selection, molding parameters and dimensional inspection before serial delivery.
Because RL-KLT boxes are returnable and recyclable, they replace single-use packaging and support low-carbon logistics. After-sales technical support and export procedures are part of the service for global customers. For wash-down programs, confirm the cleaning temperature and chemistry; we will match the material grade to the exposure.
Information we use to configure your solution
Send us the following data so we can select the correct RL-KLT model or design a new mold.
- Part dimensions, weight and fragility
- Required payload per container and maximum stack height
- ESD performance target and grounding method
- Flow path: production line, WIP, warehouse, supplier return or distribution
- Automation interfaces: conveyor, robot gripper, AGV, ASRS, barcode or RFID
- Environmental conditions: temperature, cleaning cycle, chemical exposure
- Nesting ratio, pallet pattern and return logistics
- Annual quantity, target lead time and delivery location
Frequently asked questions
What is the difference between ESD RL-KLT and ESD R-KLT?
The RL-KLT is our reinforced variant, with a stronger wall and base structure for higher stack loads and repeated handling. R-KLT is the standard KLT option; we help you select based on part weight, stacking height and logistics cycle.
Can RL-KLT containers work with automated lines?
Yes. The series is designed for good dimensional accuracy and stable stacking. Provide your conveyor or robot interface details and we will confirm the envelope, clearance and grip features in the proposal.
What customization is possible?
We support custom mold development and tailored design. This includes internal dividers, label holders, lid compatibility, colors, logos and part-specific inserts. Tooling and sample schedules depend on the order quantity and complexity.
How is ESD performance confirmed?
Our ESD products meet industrial anti-static standards for electronics and precision components. State your surface-resistance target and application environment; we will confirm the material grade and the inspection points for your acceptance sample.
Can the containers be washed and reused?
RL-KLT boxes are built for returnable logistics cycles and can be cleaned through industrial washing lines. Confirm the cleaning temperature and chemicals so we can verify material compatibility before supply.
What do you need for a quotation?
Part dimensions and weight, payload and stack height, ESD target, automation interface, flow path, annual quantity and delivery location are enough to prepare a model selection or custom mold proposal.
