Metal Balers FAQ: Specifications, Ordering and Support Questions

Whether you manage a scrap yard, run a steel plant, or source equipment for a smelting operation, choosing the right Metal Balers raises practical questions. The answers below are based on documented specifications for the hydraulic metal baler range available from OnWang Technology Hebei Co.,Ltd.

Materials & Applications

Q: Which metals and materials can a hydraulic metal baler process?

Hydraulic Metal Balers are designed to press ferrous and non-ferrous metals including steel, copper, aluminum, stainless steel, and discarded automobiles into high-density furnace charges. The same hydraulic baling technology is also widely used to compress non-metal goods such as cotton, yarn, cloth, hemp, and wool — producing uniform bales suited to container transportation.

Specifications & Model Selection

Q: What is the nominal force and production efficiency range across available models?

The model range spans from 630 kN (model DBM63) up to 3150 kN (model DBM315). Production efficiency ranges from approximately 0.9 t/h on the smallest model up to 50–60 t/h on the DBM315. Power requirements scale accordingly, from 7.5 kW to 60 kW. All models deliver a bale density of ≥ 1800 kg/m³.

Q: What press box and bale sizes are available?

Press box sizes range from 900 × 550 × 500 mm on compact models up to 2000 × 1750 × 1200 mm on the largest units. Bale size options vary by model; for example, the DBM315 produces bales up to 1000 × 500 × 600 mm, while smaller models produce bales starting around 200 × 200 × 190 mm. Multiple press box and bale dimension options exist across the range, and different force, press box size, and bale size combinations are available depending on the model selected.

Power & Site Requirements

Q: Can Metal Balers operate without mains electricity?

Yes. A diesel engine option is available for sites where an electrical motor cannot be used. This makes it possible to operate the equipment at remote scrap collection points or facilities not yet connected to a stable power grid. The standard configuration uses an electric motor; the diesel alternative is selected at the time of ordering.

Safety Features

Q: What safety features are included on hydraulic Metal Balers?

Each machine is equipped with safety warning labels and an emergency stop button. These features are standard across the model range and are intended to protect the operator during normal use and in the event of an unexpected condition during the pressing cycle.

Logistics & ROI

Q: How do Metal Balers reduce transportation and storage costs?

By compressing loose scrap into high-density bales (≥ 1800 kg/m³) with uniform external dimensions, Metal Balers increase the amount of material that fits in a shipping container, reducing per-tonne freight costs. Uniform bale dimensions also accelerate mechanized loading and simplify warehouse storage compared to unprocessed loose scrap. In smelting applications, dense furnace charges improve charging speed relative to loose material.

Cycle Time

Q: What is the single-cycle time for a hydraulic metal baler?

Single cycle times across the model range run from 80 seconds on several models (including DBM63, DBM125) up to 160 seconds on the larger models such as DBM250, DBM280, and DBM315.
