THE PRODUCT CASE / YOUR BUYING DECISION

Which shell surfaces locate the internal assembly, and which define the handling and visible finish?

A handheld shell must accommodate internal parts while presenting a consistent exterior. This CNC-machined flashlight-shell reference helps electronics buyers define end interfaces, internal clearance and longitudinal grip features before discussing material, finishing and a sample assembly.

DEFINE YOUR PART

What needs to
be in your drawing?

Reference images explain geometry. Your approved drawing and agreed inspection records establish dimensions, material and acceptance requirements.

  • Internal geometry and tool access
  • Mounting features and connector interfaces
  • Cosmetic surfaces and assembly clearances
  • Drawing number, revision, units and material grade.
  • Surface treatment, sample quantity and repeat-order needs.
Use the complete RFQ checklist
01 / REVIEW

Resolve the requirements.

Share your drawing and the features that affect function. Agree material, process scope, inspection and commercial conditions.

02 / SAMPLE

Define what approval means.

Agree the sample quantity and measurements or assembly checks required for acceptance. Record the drawing revision used.

03 / REPEAT

Control the next order.

Retain the approved specification and packaging requirements. Review design, material or finish changes before repeat production.

Read the sample-to-production guide

Questions before
your drawing review.

Can you change the dimensions or material?

This is a custom component example. Submit your required geometry and exact material grade for feasibility review; the reference image is not a fixed catalogue specification.

What quantity and lead time should I plan for?

Include both sample and production quantities plus your target date. The quotation confirms the agreed scope, price and schedule after review.

Can I send confidential drawings?

If your project needs an NDA, contact Alen before uploading confidential files. Website submission itself does not create a confidentiality agreement.

FROM COMPONENT TO PROJECT

Review the evidence. Define your part.

Start with the component geometry, then check what the drawing, sample and order records need to establish for your own part.

Send the current drawing with quantities and critical requirements. The review is the starting point for agreeing scope, quotation and sample approval.
