What to Expect

What Does On-Site Commissioning Actually Mean?

Commissioning is the process of installing, calibrating, and verifying your machine at your factory — from the moment the crates arrive to the moment qualified film rolls off the line. It is not a training session. It is a performance verification.

Phase 1

Factory Acceptance Test

Before shipment, your machine runs a 72-hour continuous test at our Zhejiang facility. Results are documented and provided to you as the FAT report.

Phase 2

Shipment & Delivery

Machine ships by sea freight in export-grade crating. Estimated transit time is confirmed at order. You are notified of the arrival date in advance so your site is ready.

Phase 3

On-Site Installation & Commissioning

Our engineer arrives at your factory and begins the 7-day commissioning process. This is the core of this page — detailed below.

Phase 4

Acceptance & Handover

Engineer and customer sign the commissioning acceptance report. Warranty period begins from this date. Your operator takes over a verified, running line.

LayerQuestar Machinery provides factory-trained on-site commissioning engineers for all blown film machine installations across 120+ countries. The commissioning period covers mechanical assembly, electrical connection verification, process parameter setup, trial production runs, and operator handover — concluding with a signed acceptance report that marks the start of the 2-year warranty period.

Site Preparation

Before the Engineer Arrives — Your Checklist

The most common cause of commissioning delays is not the machine — it is the site not being ready. Complete this checklist before the engineer's arrival date and your 7 days will be used productively.

Floor Space & Structure

  • Floor area confirmed against machine footprint drawing (provided with order)
  • Floor load capacity: minimum 5 tonnes/m² for main extruder base area
  • Floor must be level concrete — no expansion joints under machine base
  • Ceiling height: minimum 1.5× machine tower height (confirmed in spec sheet)
  • Clear access path from loading dock to installation position for forklift

Unloading & Handling Equipment

  • Forklift: minimum 5-tonne capacity with forks long enough for crate base
  • Overhead crane (if available): rated capacity per heaviest single crate — confirmed in packing list
  • Pry bars and crate-opening tools for export timber crating
  • Customer is responsible for all unloading and in-factory positioning
  • LayerQuestar engineer supervises positioning but does not operate lifting equipment
Any damage caused during unloading or in-factory movement is the customer's responsibility. Inspect all crates for shipping damage before signing the freight receipt.

Power Supply

  • Machine is built to your confirmed local power specification (voltage / frequency / phase — confirmed at order)
  • Dedicated power feed run to the machine position before engineer arrival
  • Isolator switch accessible within 3 metres of the control cabinet
  • Voltage stability: fluctuation should not exceed ±10% of rated voltage
  • Earth / ground connection in place and tested
Unstable power supply is the leading cause of VFD and temperature controller damage during commissioning. If your local grid is unreliable, a voltage stabiliser is strongly recommended before the engineer arrives.

Trial Production Material

  • Customer provides all resin for trial runs — LayerQuestar does not supply material
  • Minimum quantity: sufficient for 3 full production runs (quantity confirmed in commissioning plan)
  • Resin must match the material specification confirmed in the machine order
  • Material should be dry and at ambient temperature — not freshly delivered from cold storage
  • Waste film from trial runs is the customer's responsibility to manage

Personnel & Communication

  • Minimum 2 operators assigned to the machine must be present throughout commissioning
  • A designated contact person who can make operational decisions must be available daily
  • Our engineer communicates in Chinese — translation via phone or app is the standard working method
  • Having a team member with basic English significantly accelerates the process
  • All critical operating steps are documented with diagrams — language is not a barrier to safety
All electrical labels, HMI screens, and the operator manual are in English. Safety-critical procedures are communicated via illustrated step cards — no language required.

Utilities & Consumables

  • Compressed air supply (if machine includes air-ring or pneumatic components) — pressure per spec sheet
  • Cooling water supply for water-cooled configurations — flow rate per spec sheet
  • Basic hand tools available on site (spanners, screwdrivers, spirit level)
  • Fire extinguisher accessible within the production area
  • Waste film disposal area designated before trial runs begin
7-Day Schedule

What Happens Each Day on Your Factory Floor

This is the standard 7-calendar-day commissioning schedule. Actual progress depends on site readiness and machine configuration. The engineer does not leave until the acceptance criteria are met.

Day 1 Arrival & Unpack

Site Survey & Crate Opening

  • Engineer inspects site readiness against pre-commissioning checklist
  • All crates opened and components inventoried against packing list
  • Any shipping damage documented and reported immediately

  • Film thickness measured across width — die gap adjusted to achieve ±8% tolerance
  • Output rate measured and confirmed against contracted specification
  • Winder tension and cut length calibrated
  • Process parameters recorded and provided to customer as baseline reference sheet
Day 7 Handover

Operator Training & Acceptance Sign-Off

  • Operator walkthrough: startup, shutdown, and emergency procedures
  • Routine maintenance schedule explained with reference to operator manual
  • Common fault codes demonstrated and first-response steps explained
  • Acceptance criteria verified against the commissioning acceptance document
  • Customer and engineer sign the commissioning acceptance report
  • 2-year warranty period begins from this date
If 7 days is not enough

If the acceptance criteria have not been met by Day 7 due to machine-related issues, the engineer extends the stay at no additional labor charge. The maximum extended stay is 10 calendar days total. Additional daily living allowance of $100 USD continues to apply for each extended day.

Acceptance Standard

What Does "Commissioning Complete" Actually Mean?

Commissioning is not complete when the machine is assembled. It is complete when it meets every item on the written acceptance criteria document — verified, measured, and signed by both parties.

Output Rate

Measured output (kg/h) meets or exceeds the contracted specification under standard operating conditions with the customer's specified resin.

Film Thickness Tolerance

Thickness variation across the film width is within ±8% of the target gauge, measured at a minimum of 8 points across the lay-flat width.

Bubble Stability

Film bubble maintains stable geometry during continuous operation without manual intervention under standard ambient conditions.

Temperature Control Stability

All barrel and die head temperature zones hold within ±1°C of setpoint under stable continuous operation.

Continuous Run

Machine completes a minimum 4-hour uninterrupted production run without fault stops, producing film that meets the above criteria throughout.

Safety Systems Verified

Emergency stop, overtemperature protection, and motor overload protection all tested and confirmed functional before sign-off.

Documentation Handed Over

Operator manual, wiring diagrams, spare parts catalogue, process parameter reference sheet, and signed commissioning report all delivered to the customer before engineer departure.

Commissioning Acceptance Report

Every commissioning concludes with a signed acceptance report — a formal record that all criteria have been met. This document marks the official start of your 2-year warranty period.

The full acceptance criteria document is available for download before you place an order. We encourage you to review it as part of your supplier evaluation.

Common Questions

What Buyers Ask Before Commissioning

Questions we hear from customers planning their first installation — answered directly.

Is commissioning really free? What is the catch?

The engineer's labor — 7 days of professional time — is included in your machine contract at no additional charge. There is no catch. What you do pay for is the practical cost of getting the engineer to your country: return airfare, visa fees, accommodation, and a daily living allowance of $100 USD per day. These costs are confirmed in writing before the engineer departs, so you know the full number in advance.

What if my site is not ready when the engineer arrives?

If the site is not ready — power not connected, floor not cleared, forklift not available — the 7-day clock still starts on the engineer's arrival day. Days spent waiting for site preparation count against the 7-day period. This is why we provide the preparation checklist well in advance and recommend completing it at least 5 days before the engineer's scheduled arrival.

What if the machine still has problems after 7 days?

If the acceptance criteria have not been met due to a machine-related issue, the engineer extends the stay at no additional labor charge. The maximum total stay is 10 calendar days. During any extended days, the daily living allowance of $100 USD continues to apply. If the issue cannot be resolved on-site within 10 days, it transitions to a warranty claim and is handled through our after-sales process — replacement parts are dispatched within 48 hours from our Zhejiang warehouse.

Do I need to provide a translator?

Our engineers communicate in Chinese. Phone translation apps are the standard working method and are sufficient for most commissioning tasks. All machine labels, HMI screens, and the operator manual are in English, which helps bridge the gap. Having one team member with basic English on your side significantly speeds up communication. For safety-critical procedures — electrical connections, emergency stop sequences — our engineers use illustrated step cards that do not rely on language.

How much resin do I need to prepare for the trial runs?

The exact quantity depends on your machine's output rate and the number of trial runs required. As a general reference, plan for enough material to run the machine at full output for a minimum of 8 hours of trial production across Days 5–6. Your commissioning plan — provided before the engineer departs — will include a specific material quantity recommendation for your configuration. All trial material is provided by the customer; LayerQuestar does not supply resin.

Can I witness the Factory Acceptance Test before the machine ships?

Yes. You or your representative are welcome to visit our Zhejiang facility to witness the 72-hour FAT run before final payment and shipment. Many customers find this valuable — you see the machine running, meet the engineer who will commission it at your site, and can raise any questions before the machine leaves our factory. Contact us to schedule a FAT witness visit.

What forklift capacity do I need to unload the machine?

A minimum 5-tonne forklift is required for most configurations. The exact requirement depends on your machine model — the heaviest single crate weight is listed in the packing list provided with your order. If your facility has an overhead crane, the rated capacity should meet or exceed the heaviest crate weight. Our engineer supervises the unloading and positioning process but does not operate lifting equipment — that is the customer's responsibility.

When does my 2-year warranty start?

The 2-year warranty begins on the date both parties sign the commissioning acceptance report — the day the engineer confirms the machine meets all acceptance criteria and hands over to your operator. It does not start on the shipping date or delivery date. This means if installation takes several weeks after delivery, you still receive a full 2 years of warranty coverage from the moment your line is verified and running.
