Model and application
The TDB-120A, previously listed as TDB-120F, is a single-station accumulator-head machine for container projects up to 120 L. A 12.8 L accumulator supplies the parison, while the standard 100 mm screw is rated at 160 kg/h HDPE extrusion output.
Product and mold selection
This configuration provides 740 kN clamping force and a 900 × 1450 mm maximum mold envelope. For a tall drum or large hollow container, review neck access, wall distribution, mold cooling and part removal alongside the nominal volume. The standard machine dimensions are 6.8 × 3.4 × 4.5 m; plant layout must also allow for service access and auxiliary equipment.
Configuration comparison
The step from the TDB-50A to the TDB-120A changes more than container capacity: the accumulator increases from 6.6 L to 12.8 L and the clamp from 260 kN to 740 kN. The standard cooling-water flow also changes from 65 L/min to 180 L/min. These differences should be included in the production-line and utilities plan.
| Standard configuration | TDB-25A | TDB-50A | TDB-120A |
|---|---|---|---|
| Maximum product volume | 25 L | 50 L | 120 L |
| HDPE extrusion output | 110 kg/h | 130 kg/h | 160 kg/h |
| Accumulator | 4 L | 6.6 L | 12.8 L |
| Clamping force | 215 kN | 260 kN | 740 kN |
| Maximum mold size (W × H) | 550 × 650 mm | 700 × 950 mm | 900 × 1450 mm |

How to read the specifications
Specifications are the standard configuration in Tongda’s latest brochure (printed pages 35–36), confirmed by Tongda’s marketing department. Custom configurations require a separate specification.
- HDPE extrusion output is a mass-flow specification, not finished products per hour.
- Dry cycles describe machine cycles, not the production rate of an accepted container or panel.
- Installed power is the machine rating, not measured electricity consumption. Auxiliary equipment needs a separate utilities review.
For a production estimate, send your drawing and requirements, including resin, target part weight, dimensions and required accepted output.
FAQ
Is the TDB-120A specified for 200 L drums?
The current brochure lists a maximum product volume of 120 L for this model. A 200 L drum requires a separate model and mold review; do not infer compatibility from the accumulator-head machine category.
Does 120 dry cycles/h establish the production rate?
No. Tongda confirms that dry cycles describe machine cycles rather than finished-product output. A production trial with the specified resin, mold and container is needed to establish accepted units per hour.
Which utilities should be planned for the standard configuration?
The brochure lists 131.5 kW total installed power, 1.6 m³/min air consumption at 0.6 MPa blow pressure, and 180 L/min cooling water at 0.3 MPa. Confirm the complete line including auxiliary equipment before installation.
