Choosing Z29 Series Mechanical Vibrating Table: Application Fit and Specification Checks

What Is the Z29 Series Mechanical Vibrating Table?

The Z29 series mechanical vibrating table is a purpose-built piece of foundry compaction equipment. According to confirmed product documentation from Yonghong Machinery Group Co., Ltd., the machine is primarily designed for vibrating sand molds during resin sand and water glass sand molding. It can also handle clay sand and other self-hardened sand molds, making it a versatile choice for sand mold compacting in the casting industry.

Understanding the intended application scope is the first and most important step when evaluating this equipment for your foundry operation.

Application Fit: Is the Z29 Series Right for Your Process?

Before reviewing technical specifications, confirm that your production process matches the machine's supported use cases.

Supported Sand Types

The Z29 series mechanical vibrating table is confirmed suitable for:

• Resin sand molding – the primary design target
• Water glass sand molding – explicitly listed as a supported application
• Clay sand molding – supported as an alternative use
• Other self-hardened sand molds – the machine accommodates other self-hardening binder systems

If your foundry uses a sand system outside these categories, consult the manufacturer for application confirmation before proceeding.

Process Role

The machine's function is compaction via vibration: it consolidates loose sand around a pattern inside a flask, reducing voids and increasing mold density. It is not described in the confirmed materials as a screening, conveying or sand reclamation device. Buyers seeking those functions should review separate equipment categories.

Model Range and Specifications

The Z29 series is offered in five standard models. The following table is reproduced from confirmed product documentation:

The range covers payload capacities from 1 t to 10 t, giving buyers meaningful flexibility across small, medium and large flask sizes.

Key Selection Criteria

1. Match Payload Capacity to Your Flask Weight

Payload capacity is the most direct specification to verify. Sum the combined weight of your flask, pattern and packed sand, then select the model whose rated payload meets or exceeds that figure. For example:

• Small patterns in lightweight flasks → Z291 (1 t) or Z292 (2 t)
• Medium production cores or medium-weight flasks → Z294 (4 t)
• Large or heavy flasks typical of structural castings → Z296 (6 t) or Z2910 (10 t)

Do not operate the machine beyond its rated payload. Exceeding the rated capacity can affect compaction quality and equipment longevity.

2. Verify Table Size Against Your Flask Footprint

Every model specifies a table surface dimension. The flask base must fit within the table area to ensure uniform vibration transfer and safe operation. Key checkpoints:

• Measure the outer footprint of your largest production flask.
• Compare it against the table size for your candidate model.
• Allow clearance at the edges; a flask that overhangs the table will receive uneven compaction.

Table sizes in the Z29 series range from 1 250 × 1 200 mm (Z291/Z292) up to 2 550 × 1 500 mm (Z2910), so larger castings require the higher-payload models not just for weight but for surface coverage.

3. Assess Exciting Force Relative to Sand Density Requirements

Exciting force (expressed in kN) determines how effectively the vibration penetrates a densely packed mold. Higher exciting force is generally needed for:

• Thicker or deeper flask sections
• Binder systems that require more aggressive initial compaction
• Higher production throughput, where each compaction cycle must be shorter

The Z29 series scales exciting force from 2 × 10 kN (Z291) to 2 × 50 kN (Z2910) in step with payload, so a heavier, larger mold automatically corresponds to a model with greater force—but verify this relationship holds for your specific sand system.

4. Check Available Power Supply

All Z29 models use dual-motor configurations. Before finalising a model, confirm that your facility's electrical supply can support the combined motor power:

• Z291: 2 × 0.55 kW (1.10 kW total)
• Z292: 2 × 0.75 kW (1.50 kW total)
• Z294: 2 × 1.5 kW (3.00 kW total)
• Z296: 2 × 2.0 kW (4.00 kW total)
• Z2910: 2 × 2.5 kW (5.00 kW total)

Also verify that your site's voltage, frequency and starter circuit capacity match the motor requirements. If your facility operates on a non-standard supply, raise this with Yonghong Machinery Group Co., Ltd. during enquiry.

5. Confirm Sand Type Compatibility

The Z29 series is for resin sand, water glass sand, clay sand and self-hardened sand. Do not assume suitability based on the model's mechanical parameters alone.

What the Confirmed Materials Do Not Cover

The available documentation does not include pricing, lead times, export certifications, installation dimensions, noise ratings, or foundation loading data. Buyers who need these details—particularly for project planning, site preparation or regulatory compliance—should request them directly from Yonghong Machinery Group Co., Ltd. as part of the formal enquiry process. No assumptions about these factors have been made in this guide.

Summary: Selection Checklist

Before requesting a quotation for the Z29 series mechanical vibrating table, work through the following checklist:

1. ☑ Your process uses resin sand, water glass sand, clay sand or a compatible self-hardened sand.
2. ☑ You have calculated the combined weight of flask + pattern + sand and identified the appropriate payload model.
3. ☑ Your largest flask footprint fits within the table size of the selected model.
4. ☑ Your electrical supply matches the dual-motor power requirement of the selected model.
5. ☑ You have noted any non-standard requirements (unusual binders, atypical flask geometry, site constraints) to discuss with the manufacturer.
