Special machine builder

A family-owned special machine builder as a walkable model: how a custom packaging line moves from enquiry to site acceptance and where the 28 weeks go.

All data are fictional, including lead times and hours. The model can be adapted to your company's real data and filled with information that no report brings together today – for example project status from the ERP, or supplier lead times.

This engineer-to-order process simulation is built around the fictional VELBROCK MASCHINENBAU, a family-owned company with seven buildings and 21 departments. Every line is one of a kind – first designed, then made, assembled, accepted with the customer and shipped around the world.

The main process follows a packaging line for a frozen pizza maker, 120 cartons per minute: proposal, specification, mechanical and electrical design in parallel, bill of materials released in PDM, parts manufacturing and purchasing, assembly under the hall crane, factory acceptance test (FAT), CE marking, seaworthy packing, loading and site acceptance test (SAT). Model target: shipped almost 28 weeks after the enquiry, about 22 weeks after the order.

Spare parts, service calls for stopped machines and customer change requests run alongside. The page addresses owners and managing directors, project, design and plant managers, sales, HR and training.

  7. 07

    Kick-off and specification: Project management and customer write the specification: formats, output, interfaces.

  8. 08

    Mechanical and electrical design work at the same time.

  9. 09

    Basic design (lead designers): A lead designer fixes the machine concept: layout, drives, format change.

  10. 10

    Detail design and drawings: The team draws frame, format parts and guards in CAD – thousands of parts.

  11. 11

    Electrical design and PLC: Wiring diagram, safety concept and PLC program are created.

How a machine builder can use the model

  • Internal communication

    Administration, engineering, parts manufacturing, assembly hall, logistics centre and loading yard visible together. The collaboration view shows how sales, design, purchasing and assembly all hang on one order.

    対象Management, works council, managers

  • Onboarding

    New designers, fitters and project managers see what happens before and after their own step – from the enquiry to the signature on the site acceptance.

    対象New staff in design, assembly and project management

  • Training

    Apprentices follow a line through the plant and see what an electronics shortage or missing designers set off. ‘The path across the site’ shows manufacturing, assembly and loading.

    対象Training managers, apprentices, work-study students

  • Explaining to customers

    Why does a special machine take months? The model shows customers the whole order, where the 28 weeks go and what factory (FAT) and site acceptance (SAT) mean.

    対象Sales, project managers, customers

  • Strategic overview

    Engineering offices, modular kit, assembly shifts, spare parts stock: the model compares the levers for lead time. The trade fair effect shows when design capacity fills up.

    対象Owner family, advisory board, management

Departments in the model

  • Shareholders and advisory board

    The family holds the shares in its third generation; an advisory board advises management and approves large investments.

  • Management board

    Two managing directors: technical and commercial. One of them from the family.

  • Sales and proposals

    Qualifies enquiries, drafts a concept with design and prices the proposal.

  • Project management

    One project manager per order: specification, schedule, changes, contact with the customer up to acceptance.

  • Mechanical design

    Designs every machine new or from modules – frame, conveying, tooling, guarding.

  • Electrical design and software

    Wiring diagrams, safety technology and the PLC programs the machine will run on.

  • Plant management

    Leads manufacturing, assembly and commissioning.

  • Production planning

    Turns the bill of materials into work orders, NC programs and the assembly plan.

  • Purchasing

    Orders bought-in parts – about two thirds of a machine's material value comes from suppliers.

  • Parts manufacturing (CNC)

    Mills and turns individual parts on machining centres – often batch size one.

  • Sheet metal and welding

    Laser cutting, bending and welding of frames, panels and guards.

  • Assembly

    Builds the machine on fixed assembly bays under the crane – weeks per line.

  • Electrical assembly

    Builds control cabinets and wires sensors, drives and safety equipment on the machine.

  • Commissioning

    Loads the software, runs the machine in, holds acceptance with the customer and commissions it on site.

  • Quality assurance

    Measuring room, checks of supplied parts and the CE documentation – reports directly to management, not to the plant manager.

  • Service

    Hotline, remote support and technicians who travel worldwide to stopped machines.

  • Spare parts

    Identifies the part, ships from stock or has it made urgently.

  • Logistics and shipping

    Goods in, storage, crating and loading.

  • HR and apprenticeships

    Hiring, shift plans and about 45 apprentices in the in-house training workshop.

  • Controlling, finance and IT

    Post-calculation of every order, liquidity, down payments and IT.

  • Works council

    Elected by the employees: co-decides on shifts, overtime and agency work.

A spare part is needed

  1. 01Identify the spare part: A customer orders a blade for the carton cutter – the machine is twelve years old.
  2. 02Rush job on the machine: Not in stock: parts manufacturing squeezes the part in between project parts.
  3. 03Pick the spare part: The store picks and packs the part.
  4. 04Parcel pick-up (5 pm): At 5 pm the parcel service collects.
  5. 05Delivery to the customer: The next day the part is at the customer.
  6. 06Delivered.

A machine stops at a customer

  1. 01Customer reports a stoppage: At three in the morning the line stops at the customer: fault at the carton erector.
  2. 02Hotline and remote diagnosis: The hotline connects to the controller remotely.
  3. 03Solved remotely.
  4. 04Dispatch a technician: Dispatch looks for a free technician with the right experience.

  6. 06Send the part by courier: The spare parts store sends the part by courier.
  7. 07Service report and invoice: Service report, hours and parts go to invoicing.
  8. 08The machine runs again.

A customer changes the order

  1. 01Customer requests a change: In the middle of assembly the customer wants an extra format: a larger pizza.
  2. 02Assess the change: cost and schedule: Project management assesses cost and schedule impact.
  3. 03Customer decides on the variation: The customer decides on price and new date.
  4. 04The contract stands.
  5. 05Change design: Design changes format parts and bill of materials.
  6. 06Implement the change in assembly: Assembly fits the changed parts.
  7. 07Change implemented.

What you can change

Controls

  • Order intake: How many enquiries arrive. After a major trade fair there are many more.
  • Design capacity: Designers are scarce. Engineering offices take on packages – for money and with coordination effort.
  • Modular kit: Reusable modules: less design time and fewer defects at acceptance (model assumption).
  • Assembly shifts: More assembly bays staffed at once – the works council co-decides.
  • Spare parts stock: More parts in stock: fewer rush jobs, but more capital tied up.

Disruptions

  • ERP outage: Four hours without ERP: no orders are created, no spare part is found.
  • Electronics shortage: For two months controls and drives take almost twice as long – assembly waits for parts.
  • Absences in design: For a month a quarter of the designers are missing – flu wave and resignations.
  • Trade fair effect: For two weeks after the trade fair twice as many enquiries arrive.

What a machine builder gets out of it

  • 01

    A plant you can walk through

    Seven buildings from engineering to the loading yard, every hall and floor can be opened. An order travels as a point of light from station to station.

  • 02

    Parallel work made visible

    Mechanical and electrical design, purchasing, manufacturing and cabinet building run at the same time in the simulation. If a part is missing, assembly waits – and you can see it.

  • 03

    Relieve design – in the model

    Five controls and four disruptions, from the modular kit to an ERP outage. A hint at the bottleneck names the control that helps and sets it at the press of a button.

  • 04

    Diagrams in step with the simulation

    14 diagrams in four groups calculate live – for example how much of the lead time goes to design and suppliers.

  • 05

    For trade fair, customer meeting and shop floor

    The model needs nothing but a browser and also holds up on large projections. A guided tour in eight steps explains it the first time you open it.

  • 06

    Designed, not configured

    Created by an artist and developer. An overview shows 35 more organisations, including a car maker, a chemicals group and a chip maker.

Basis and limits

Fictional company · model based on researched industry structures · no statement about real companies

1 case = 1 enquiry or machine, 1 spare part order, 1 breakdown or 1 change · 1 figure ≈ 10 employees

All volumes, durations, rates and capacities are model assumptions, not values of a real company.

Stations work every day in the model; weekends only affect the volume of cases, summer plant holidays act as slower design and assembly.

Documented: CE marking and declaration of conformity by the manufacturer, acceptance in the plant (FAT) and at the customer (SAT) as usual project steps, co-determination on shifts.

Public sources the model is based on:

  • VDMA – Verband Deutscher Maschinen- und Anlagenbau
  • VDMA Fachverband Nahrungsmittel- und Verpackungsmaschinen
  • Destatis: Auftragsbestand im Verarbeitenden Gewerbe
  • Maschinenverordnung (EU) 2023/1230
  • Maschinenrichtlinie 2006/42/EG
  • DIN EN ISO 12100 (Risikobeurteilung) und DIN EN 60204-1 (elektrische Ausrüstung)
  • Berufsbildungsgesetz (BBiG)
  • Betriebsverfassungsgesetz § 87
