A request for a quotation on automotive-parts production equipment often arrives with one sentence and an attachment: "we need a line for brackets, please quote." At the other end of that message, an engineer has to decide what the machine actually has to do. The gap between those two positions is where most quotation delays come from. When the buyer sends a clear data set, the first reply can include a realistic layout, a stated cycle-time assumption and a price range. When it does not, the reply is a list of follow-up questions and the project waits another week.
The information below is the set that PowerDe's automation and automated production line work normally needs before a layout can be drawn. It applies whether the enquiry is for a machining cell, a joining and assembly station, or an in-process cleaning step beside the line.
Start with the part, not the machine
The part definition comes first. A drawing with tolerances tells the supplier what has to be held; a part name alone does not. For metal components, send the material grade and the condition of the incoming stock, because bar stock, stamped blanks and cast blanks call for different handling and clamping. Photos of one or two representative pieces, taken from more than one side, usually settle questions that the drawing leaves open, such as burrs, oil film, or a datum face that has already been machined.
If the part family is still changing, say so. A line built around one drawing will need retooling when that drawing is revised, and the supplier can only design in flexibility if they know the design is not frozen. State which dimensions are final and which are still moving.
State the volume figures the supplier can use
"High volume" means different things in different plants, and the same phrase does not tell an engineer how many stations to draw. Give annual volume for the part, the number of shifts per day, the length of a shift, and whether the plant runs five or seven days a week. Add the required output per hour, or the takt time, so machine count and cycle times can be checked against it.
Also state the ramp profile and any changeover between part numbers. A line that must reach full output within eight weeks of delivery is built differently from one where output rises over a year. Where two bracket variants share the same station, the changeover time is a requirement, not an afterthought; if a changeover must be completed inside a set window, say what that window is. If prototype or pilot quantities are needed before full production, mention them, because small pre-production lots are often handled through fixtures and program recipes rather than through a separate line.
Describe the process steps you already have
Parts for vehicles usually pass through several unrelated processes before they can be assembled: cutting and forming, machining, joining, protective coating, and assembly. List the operations in order, and for each one say whether it is inside the scope of the enquiry or belongs to equipment you already own. A line that ends with an in-process cleaning step is specified differently from a line that hands oily parts to a separate wash hall.
Cleaning and oil removal are frequently left out of the enquiry and added later as a change order. If blanks arrive coated with drawing lubricant or cutting fluid, and the parts must be dry and oil-free before welding, adhesive bonding or plating, put that requirement in the first message. It also determines where a machine sits: a fixed industrial steam cleaner can stand beside an assembly bay and uses ordinary 220 V supply, tap water and a floor drain, which is why this type is considered when cleaning belongs to the line rather than to a central wash hall. State the service conditions of the space - available power, water supply, drainage, floor loading and whether the area is indoors - so the utility list is settled at the same time as the machine.
Give the quality and inspection requirements
Say what is measured, how often, and by what method. A dimension checked on a coordinate measuring machine off the line is not the same requirement as a gauge or vision check performed in the station. If parts are for a safety-related assembly, or if traceability of a serial number or lot code is required, state it, because marking, reading and data recording change both the equipment list and the control software. Where the customer's own drawing carries the inspection plan, attach it instead of summarising it.
Provide the utility and space envelope
A quotation for production equipment is also a quotation for the installation. Send the available floor area with the clear height, the position of the existing aisles, and the point where material enters and leaves. Then list the services at that point: voltage and frequency, compressed-air pressure and flow, water supply and drainage, and any extraction or ventilation requirement. Electrical standards differ by country, so state the supply voltage and frequency of the plant rather than assuming the supplier will guess. If the machine must pass through a door of a certain width or be moved in sections, say so before the frame is designed.
Explain how the line will be operated and maintained
Operator skill level, language of the interface, and who performs maintenance all affect the design. A plant with one technician and limited spare-part stock benefits from standard, locally available components and a control layout that can be taught in a shift. If the line runs overnight, tell the supplier whether an operator is present, because unattended running changes the guarding, restart logic and fault handling. If a changeover between part numbers must happen within a set time, give that time; quick-change fixtures and recipe-based setup are design choices, not defaults.
Set the commercial terms you need in the offer
State what the supplier should include: design, manufacture, factory acceptance test, installation, commissioning, training, spares, and the acceptance criteria that define completion. Give the required delivery date and the date the line must be producing saleable parts, since these are usually different. If the buyer is arranging freight, say so; if the supplier is responsible for delivery to the plant, the packing and transport dimensions become part of the design. A written scope list avoids the situation where two quotations look different in price but cover different amounts of work.
A short pre-quotation checklist
1. Part drawing with tolerances, material grade, and photographs of a finished sample.
2. Annual volume, shifts per day, hours per shift, days per week, and target output per hour.
3. Process steps in scope and steps that stay on existing equipment.
4. Cleaning, drying and oil-removal needs, including the condition of incoming and outgoing parts.
5. Inspection method, frequency, traceability and marking requirements.
6. Floor area, clear height, door and aisle limits, and local floor loading.
7. Voltage, frequency, compressed air, water, drainage and ventilation at the installation point.
8. Changeover time between part numbers, staffing, and who performs maintenance.
9. Delivery date, production start date, and the division of responsibility for installation and training.
10. The acceptance criteria that will be used to close the project.
Collect these items before the enquiry goes out and the first reply from a supplier will normally contain a layout and a price band rather than a questionnaire. If a figure is genuinely unknown, write "to be confirmed" next to it. That tells the supplier which questions are open and which answers are firm, and it keeps the quotation moving.
