When searching for ESD injection moulded packaging, customers usually do not need a completely new box. They want to find an existing product whose size, structure, and handling method are close as quickly as possible. Rather than starting with a new-tooling discussion, it is more efficient to screen Yufa's existing specifications against the product dimensions, loading quantity, handling habits, and ESD requirements, and then complete the solution with a lid, dividers, a label holder, or foam.

1. New Tooling Is Not the First Step: Find the Closest Existing Size

When selecting an injection-molded product, comparing external dimensions alone is not enough. What really determines suitability is the usable internal dimensions, the height of the box or tray, the orientation of the product, the clearance for loading and removal, and the way the packaging is stacked and circulated. A close dimension does not mean the product can be used directly, but it is a valid starting point for initial screening.

• The product fits securely but there is slight clearance around it: consider adding EVA, IXPE, or EPE foam.

• Several products must be placed in the same box: consider injection-molded dividers, die-cut slotting, or foam cells.

• Dust protection, stacking, or label management is required: confirm the lid, label holder, and extension frame options at the same time.

• Only when the existing specification is clearly unsuitable should other custom packaging be considered, rather than sacrificing handling efficiency or protection just to stay close to a size.

3. How to Screen Existing Molds Quickly

1. Define the handling method first.  Will the product be used for transport, storage, process transfer, or picking at the production line? Does it require frequent loading and removal, stacking, or repeated circulation?

2. Confirm the usable internal dimensions next.  External dimensions make searching easier, but the actual match should be based on product dimensions, orientation, operating clearance, and usable internal dimensions.

3. Then confirm the structure and accessories.  Whether a lid, dividers, a label holder, an extension frame, a hole pattern, or foam is needed will affect the final model selected.

4. Shortlist candidates by product code.  The product code contains the category, material family, external dimensions, and any necessary structural features, which makes communication and verification faster.

5. Verify with a sample before mass production.  For projects with tight fit tolerances, a specific handling feel, or demanding stacking requirements, a sample or a trial packing run is recommended before confirmation.

4. Common Search Requests and How They Map to Existing Products

Customers often search by size plus application. Yufa's existing products can be screened against the following requests:

• 600 x 400 ESD injection-molded box: the catalog covers several heights and structures; the lid, dividers, label holder, or extension frame can be confirmed further.

• 400 x 300 and other ESD turnover boxes: suitable for finding a close specification within an existing production line, shelving, or circulation system.

• 380 x 310 ESD tray: can be screened by solid base, fully perforated, perimeter-perforated, and different heights.

• ESD compartmented tray: used for batch placement and sorting management; whether each cell suits the product still needs to be confirmed.

• 7-inch or 13-inch SMT reel box: choose from three existing formats according to reel diameter and loading quantity.

5. Using Product Codes to Handle Specific Inquiries

Existing injection-molded products use a coding system of category + material segment + external dimensions + necessary features. A customer can simply quote the product code, and Yufa will then help confirm the usable internal dimensions, material, resistance range, and available accessories.

The code shortens the communication path, but it does not replace project confirmation. The material segment in the code distinguishes the material families listed in the catalog; the actual material name, surface resistance range, and applicable conditions are subject to the corresponding product entry and project confirmation.

6. Resistance Range Also Needs to Be Confirmed Item by Item

This series covers only injection-molded products with an ESD function. The existing catalog contains two material families, ESD PP alloy and ESD PP, with surface resistance ranges of 10⁴–10⁸ Ω and 10⁵–10⁹ Ω respectively for the products listed under them. Not every size can be supplied in either range; the specific material and ESD parameters must be confirmed against the product code.

7. Frequently Asked Questions

Q: Do we have to open a new mold?

A: Usually new tooling does not need to be considered first. Yufa will look for a close solution within the existing specifications; only when the existing products cannot reasonably meet the dimensional, structural, or handling requirements will other options be discussed.

Q: Can we place an order as soon as we find a box with similar external dimensions?

A: Not advisable. The usable internal dimensions, product orientation, loading clearance, stacking method, and available accessories still need to be confirmed.

Q: Can foam be added to an existing injection-molded box?

A: EVA, IXPE, or EPE foam can be evaluated for each project for positioning, cushioning, and contact-surface protection.

Q: Should the website publish the complete catalog?

A: A condensed customer PDF catalog is recommended rather than the Excel source file. The catalog helps customers screen by size and product code, while the specific project is still confirmed by email.

8. How to Start the Selection Process

If a close product has already been found, send the product code and the estimated quantity. If the model is not yet clear, simply provide the following information:

• Product dimensions or the usable internal dimensions required

• Loading quantity and product weight

• The application: transport, storage, process transfer, or picking at the production line

• Whether a lid, dividers, a label holder, or foam is required

• The target ESD requirement and any other mandatory conditions
