Why should factory utilities be prepared before delivery?

A blow molding machine needs suitable factory conditions before installation and commissioning can begin. Air, water, power, floor space, access routes and maintenance clearance all influence the installation process.

If the buyer waits until the machine arrives to review these requirements, installation may be delayed by missing connections, insufficient capacity or an unsuitable layout. Preparing the factory in advance gives the buyer and supplier a clearer starting point for commissioning.

The exact requirements vary by machine model, mold, auxiliary equipment and destination‑market conditions. The supplier's technical documents should always take priority over a general checklist.

1. Confirm the electrical supply

The buyer should confirm the electrical requirements with the supplier before preparing the machine area. The review may cover the required supply type, voltage, frequency, protection devices, cable route, cabinet position and grounding arrangement.

Prepare and verify:

• Factory supply conditions
• Main electrical protection
• Cable route and connection position
• Control‑cabinet access
• Grounding arrangement
• Space for inspection and maintenance
• Requirements for auxiliary equipment
• Local electrical installation rules

Do not assume that a machine purchased for one country uses the same electrical configuration in another country. The final electrical specification should come from the approved technical proposal and machine documentation.

2. Plan cooling water and drainage

Blow molding machines and molds may require cooling‑water connections for process stability. The factory should understand where water enters and exits the machine or mold, how the circuits are connected and how maintenance or drainage will be managed.

Discuss with the supplier:

• Water supply location
• Return‑water route
• Water temperature‑control equipment
• Flow and pressure conditions
• Cooling connections for the mold
• Drainage and spill management
• Water quality and filtration needs
• Space for pumps, chillers or auxiliary units where applicable

These requirements are application‑specific. A generic water connection cannot guarantee that a particular machine or mold will operate correctly.

3. Confirm compressed‑air requirements

Compressed air may be used for blowing, product take‑out, valves or auxiliary equipment, depending on the machine configuration. The buyer should confirm the required supply conditions and the location of the air connection before delivery.

Review:

• Air‑supply location
• Pressure and flow requirements from the supplier
• Air filtration and drying
• Pipe routing and connection type
• Condensate management
• Requirements for high‑pressure or low‑pressure circuits where applicable
• Safety and isolation procedures

The final values should be taken from the machine's technical documentation. Do not use a general industry figure in the installation plan unless the supplier has confirmed it.

4. Check the floor, foundation and access route

The machine needs a suitable location, stable support and enough space for installation and maintenance. The delivery route should also be checked before the equipment is packed and shipped.

Review:

• Floor condition and level
• Foundation or anchoring requirements
• Machine footprint and service clearance
• Door and passage dimensions
• Crane, forklift or lifting access
• Delivery route from unloading point to production area
• Space for mold installation and removal
• Storage location for accessories and spare parts

The machine dimensions and weight must come from the approved project documents. A general factory‑layout assumption is not enough for a safe delivery plan.

5. Prepare the auxiliary‑equipment layout

The main machine may work with molds, chillers, compressors, dryers, grinders, conveyors, take‑out devices or other auxiliary equipment. The layout should show how material, utilities, products and operators move through the production area.

Before delivery, define:

• Position of the main machine
• Location of auxiliary equipment
• Material loading and storage path
• Finished‑product removal path
• Operator work area
• Maintenance access
• Utility connection route
• Safety and emergency access

A compact layout is not necessarily an efficient layout if operators cannot reach maintenance points or finished products cannot move safely.

6. Create a pre‑installation communication checklist

The supplier and buyer should agree on the information needed before installation. This can include photographs of the prepared site, utility confirmation, foundation drawings, lifting arrangements and contact details for the installation team.

Useful questions include:

• Which utilities must be ready before the machine arrives?
• Which components need special lifting or storage?
• What installation tools are required?
• Which documents should be reviewed by the buyer's electrician or engineer?
• When should the supplier receive site photographs?
• Who will handle first power‑on, mold installation and trial production?

Dawson support for installation planning

Dawson Machinery & Mould Group Co., Ltd. publicly lists extrusion blow molding machines, jerry can machines, molds and auxiliary equipment. Customers can discuss the product, machine configuration, mold requirements, factory layout and delivery preparation before shipment.

A successful installation begins with accurate information. The final air, water, power, foundation and space requirements should be confirmed from the selected machine and project documentation.

Final pre‑delivery checklist

Before the machine is delivered, confirm:

• Electrical supply and grounding are reviewed.
• Cooling‑water supply, return and drainage are prepared.
• Compressed‑air requirements are confirmed.
• Floor, foundation and anchoring information is available.
• Delivery route and lifting access are suitable.
• Maintenance clearance is reserved.
• Auxiliary‑equipment locations are planned.
• Installation contacts and responsibilities are clear.

Factory preparation reduces avoidable delays and gives the installation team a safer, more organized starting point. Always use the supplier's approved documentation for the final technical values.

Frequently Asked Questions

What utilities does a blow molding machine usually need? Depending on the configuration, a machine may require electrical power, cooling water, compressed air, drainage and space for auxiliary equipment. The exact requirements must be confirmed from the selected machine documentation.

Should the factory prepare the foundation before delivery? If the project requires a specific foundation, anchoring or floor preparation, it should be completed or verified before delivery. Confirm the requirements with the supplier using the approved machine drawings.

Why is maintenance clearance important? Operators and technicians need safe access to the control cabinet, moving areas, mold, utilities and service points. Insufficient clearance can make installation and maintenance more difficult.

Can the same utility plan be used for different machine models? No. Utility requirements can vary with machine model, mold, product, auxiliary equipment and destination‑market electrical conditions. Prepare the plan from the actual project documents.

What should I send the supplier before installation? Site photographs, layout drawings, utility information, foundation details, delivery‑route information and contact details for the installation team can help the supplier prepare more effectively.
