In short
Chemical Drum: what to know
Plastic chemical drums, including closed-head L-ring drums and open-top drums, are blow molded from HMW-HDPE on accumulator-head machines. Tongda’s TDB series covers drums from 20 L to the 200–220 L class, with single- and multi-layer configurations.
The TDB range covers several container sizes. Define the chemical, resin, closure, product weight and handling requirements before selecting a drum machine. Product-specific testing and any transport approvals form a separate part of the container project.
Typical products
- 200–220 L L-ring drums
- Double-ring and open-top drums
- 50–120 L chemical drums
- Wide-mouth barrels
Materials
- HMW-HDPE
- Multi-layer HDPE
Production process
How the production line works
- Step 01
Prepare HMW-HDPE
High-molecular-weight HDPE is dosed with masterbatch for the drum specification.
- Step 02
Accumulate the melt
The accumulator head stores melt so a heavy parison can be pushed out quickly.
- Step 03
Form the rings
The mold closes and forms the body, L-rings and bungs as the drum is blown.
- Step 04
Cool
Large drums need sufficient cooling time to stay dimensionally stable.
- Step 05
Deflash
Top and bottom flash is removed and the bungs are finished.
- Step 06
Test
Weight, leak and drop tests are carried out to the drum specification.
Selection guide
Choosing a machine
Drum design
Single-ring, double-ring or open-top designs need different molds and platen sizes.
Layers
Single-, double- or three-layer walls change the extrusion and head arrangement.
Approvals
Product testing and any transport approvals are a separate step for the finished drum.

Questions from buyers
FAQ
Didn't find your answer?
Ask our engineersWhich machine makes 200 L chemical drums?
The TDB-250F is the reference model for 200–220 L single-ring, double-ring and open-top drums.
Which machine for 50–120 L drums?
The TDB-80F covers 50–80 L products and the TDB-120F covers 80–120 L, both with accumulator heads and bottom blowing.
Are the drums approved for dangerous goods?
Approval applies to the finished drum design and its tests, not to the machine. Plan any required certification with your drum design.
