Custom Plastic Storage Containers Built for Global Logistics
Suzhou He Cheng Feng Esd Circulation Box Co., Ltd. is a China-based manufacturer and supplier of reusable plastic logistics packaging. Since 2013, we have produced ESD, conductive and foldable circulation boxes, EU/HP standard containers, plastic pallets and related accessories. We provide custom mold development for clients whose parts or processes require a non-standard container, and we support one-stop procurement for plant-wide material flow.
The Custom Plastic Storage Containers range on the category covers the KLT container families used for component handling, line-side supply and warehouse storage, plus pallets and accessories for complete unit-load packaging. Our containers are specified across electronics, automotive, pharmaceutical, food, hardware, chemical and apparel industries.
Product Range and Application Fit
We organize the catalog into three product families. The first, ESD KLT Container, is our main line for electrostatically sensitive components. It is complemented by plastic pallets and plastic accessories for plants that need a matched logistics system.
ESD KLT Container Series
ESD KLT containers are conductive bins designed for safe handling, storage and transport of electrostatic-sensitive assemblies. We produce five subfamilies to match different load, stacking and automation requirements:
- ESD R-KLT Container – reinforced sidewalls and base for higher load-bearing capacity and demanding industrial logistics.
- ESD RL-KLT Container – reinforced construction with optimized internal volume and high dimensional accuracy for production, warehousing and distribution.
- ESD C-KLT Container – KLT crates for automotive parts transport, including designs compatible with VDA-standard lids.
- ESD M-KLT Container – stackable containers for workshop and warehouse storage.
- ESD KLT Container Lid – moisture-proof sealed lids and VDA-standard anti-static lids for closed-loop handling.
Pallets and Plastic Accessories
Our Pallets family covers plastic pallets for transport and warehouse unit loads. Plastic Accessories include lids, label holders and complementary items that make the container system ready for production use. Together they support one-stop sourcing from a single China supplier.
Range Selection at a Glance
| Product Family | Positioning | Typical Application |
|---|---|---|
| ESD R-KLT Container | Reinforced conductive container for heavy-duty handling | Automotive parts, electronics, semiconductor workshops |
| ESD RL-KLT Container | Reinforced with optimized internal volume; high dimensional accuracy | Production line material handling, warehouse stacking, distribution |
| ESD C-KLT Container | Automotive KLT crate with VDA-compatible lid options | Automotive parts transportation and traceability |
| ESD M-KLT Container | Stackable ESD container for plant-side storage | Workshop and warehouse use |
| ESD KLT Container Lid | Moisture-proof sealed and VDA-standard anti-static lids | Closed-loop handling and humidity-sensitive parts |
| Pallets and Plastic Accessories | Unit-load base and matching accessories | Plant-wide material flow and returnable packaging systems |
Industry Fit and Material Approach
We select the container geometry and material grade around the process risk and handling cycle. The same KLT platform can be specified with anti-static protection for electronics, food-contact materials for food processing, or reinforced walls for heavy automotive components.
- Electronics: anti-static and conductive containers protect PCBs, chips and precision components from electrostatic discharge in ESD-controlled environments.
- Automotive: EU/HP standard and KLT containers support sorting, line-side delivery and part traceability.
- Pharmaceutical and Healthcare: containers with hygiene and cleanliness features support contamination-free handling of medicines and medical supplies.
- Food and Beverage: food-grade boxes use food-contact safe materials for handling, transport and storage.
- Hardware and Machinery: impact-resistant containers and pallets protect heavy parts, tools and components.
- Chemical: chemical-resistant, leak-proof and corrosion-resistant designs are available.
- Apparel and Textile: lightweight, stackable and foldable containers optimize warehouse space and inventory management.
Customization, Mold Development and Configuration
Standard containers cover most logistics needs, but we also support custom mold development. When you need special internal dimensions, dividers, label holders, stacking or nesting geometry, color coding or branding, our mold team develops the design and confirms the production route before quotation.
Our technical and sales groups cooperate closely to analyze the application scenario. For a new mold, we confirm the working point, material behavior and target production volume; for existing tooling, we match the closest standard model and identify any modifications. In both cases, container design is aligned with the customer conveyor, rack or line-side interface.
Automation and Line Integration
ESD KLT containers in the range are designed to work with automated production, warehouse and conveyor systems. Stable stacking, nesting performance and dimensional accuracy allow containers to pass through automatic feeding stations, storage racks and return loops without manual intervention.
When you submit a project, include the conveyor width, rack pitch, robot gripper envelope or AGV load dimension if known. We use those values to verify that the selected container or custom mold will fit the material flow system.
Quality Assurance and Acceptance
We apply rigorous production standards across mold development, injection molding and post-production checking. Our ESD products are qualified for electronic industry use and meet industrial anti-static standards; food-grade boxes are produced from food-contact safe materials.
For serial supply, we provide after-sales service and technical support. Before shipment, containers are checked for dimensional consistency, stacking behavior, surface condition and ESD material performance according to the applicable specification.
Information We Use to Configure Your Solution
To prepare a configuration and quotation, we need the operational parameters that define the container. The table below shows the typical project inputs.
| Project Input | Why It Matters |
|---|---|
| Part dimensions and unit weight | Determines internal size, wall thickness and stacking load. |
| ESD classification and handling environment | Selects conductive or anti-static material grade and surface performance. |
| Temperature, chemical or food-contact exposure | Defines material selection, sealing options and cleaning method. |
| Conveyor, rack or automated line interface | Drives dimensional accuracy, stacking geometry and automation compatibility. |
| Order quantity and delivery region | Determines standard tooling versus new mold, plus packaging and export scope. |
