Engine & cooling parts.
Prepare the packed part.

How the part family changes the brief

Pumps, thermostats and cooling parts can have irregular outlines, ports and fittings. The bag must fit the complete packed part and work with the outer carton rather than replace it.

Packaging risks to review

• Fittings and housings can create pressure points.
• Residual coolant or oil can affect the pack and print.
• A shaped part can leave unused space that allows movement.
• A label on a curved or oily surface may not stay readable.

Information worth sending first

• Dimensions of the complete assembled part
• Fittings, mounts and exposed surfaces
• Oil, water or other contact requirements

Bag format discussion

Start from how the pack is filled, carried, opened and stored. A flat bag, handled bag, zip-seal bag or easy-tear bag may each be discussed, but the format name does not establish dimensions, film or performance. Disclose any special contact, cleanliness or barrier needs instead of assuming a generic film meets them.

Sample and verification checklist

1. Measure the assembled part with caps or protection fitted.
2. Disclose any residual fluid or cleanliness requirement.
3. Test fit and removal with the real component.
4. Confirm label placement and the outer carton arrangement.

What needs project confirmation

Film grade, thickness, usable opening, print layout and special performance are reviewed together. Sampling is available; scope, timing and cost are agreed individually. Production timing and commercial terms remain subject to quotation. Requests for ESD, corrosion, barrier, cleanliness or fluid-contact performance need an explicit technical review.

Preparation questions before an RFQ

Before asking for a price, record the packed outline, the number of pieces in one pack and the condition in which the part arrives. State whether it is dry, oiled or handled with gloves, and whether the pack is opened once or more often. These details change the discussion more than a generic material name.

Keep a photo or drawing tied to the part reference. A vehicle model or catalog image can help identify the component, but it does not replace packed measurements. If a current bag is in use, send its measured dimensions and note what works or fails.

How to compare a sample

Compare samples with the same component and pack quantity. Check the opening, seam, closure and label after filling, then repeat the handling step that matters for the route. Write down the result and keep the sample reference with the artwork version so a later change is not confused with an approved arrangement.

Transit protection remains a separate question. A flexible bag can contain and cover the part, while an outer carton, divider or other support controls movement and external load. Review the complete packing system before treating a bag trial as a transit result.
