Project Requirements & Cost Comparison
Define your specification, compare the quoted scope and prepare your RFQ in one place.
Material & finishRequired recordsDelivery scope
YOUR MATERIAL. YOUR FINISH. YOUR ACCEPTANCE RECORDS.
Material & Documentation Requirements
Define the grade, coating and evidence your buyer needs before the quote is agreed.
Compare the Same Material Condition
Typical uncoated rod-and-bar reference values—not LK MFG test results or acceptance limits.
| Alloy & temper | Brinell hardness | Yield strength | Tensile strength |
|---|---|---|---|
| 6061-T6 / T651 | 95 HB | 276 MPa | 310 MPa |
| 2024-T4 / T351 | 120 HB | 324 MPa | 469 MPa |
| 7075-T6 / T651 | 150 HB | 503 MPa | 572 MPa |
Kaiser Aluminum typical data: 0.500-inch tensile specimen; Brinell 500 kg / 10 mm ball. Product form, section, temper and test method matter. Confirm the ordered material specification and heat/lot certificate. Do not treat HB, HRC, HV or Shore D as interchangeable.
Other material families: what should your drawing define?
304 / 316 stainlessGrade, product form, delivery condition and corrosion environment.
4140 alloy steelHeat-treatment condition, hardness scale/range and test location.
POM / PA / PC / ABSExact resin grade, reinforcement, moisture conditioning, temperature and chemical exposure.
Specify Thickness Before You Approve the Fit
A finish name alone does not define the final dimensions, wear behavior or appearance.
Conventional Anodizing
≈ 2.5–25 µmPublished process reference range. Agree color, sealing, thickness tolerance and cosmetic sample.
Hardcoat Anodizing
≈ 25–127 µmAAC general reference range. Define wear needs, alloy, sealing, masking and final mating dimensions.
Chemical Conversion
Type + ClassClass 1A: corrosion protection. Class 3: low electrical contact resistance. Specify chemistry type and required tests.
These are published process reference envelopes, not MIL acceptance limits or a promised LK MFG range; they overlap and depend on alloy/process. Your drawing and agreed specification govern. MIL-PRF-8625 is the current designation of the former MIL-A-8625. MIL-DTL-5541 is chemical conversion, not hard anodizing.
| Finish | Define in your RFQ | Evidence to agree |
|---|---|---|
| Anodize / hardcoat | Specification revision, type/class, µm, sealing and masking | Thickness locations, appearance sample and required tests |
| Powder coating | Coating system, dry-film thickness, color, gloss and texture | Approved sample and specified adhesion/corrosion testing |
| Plating / passivation | Substrate, exact process, specification and local thickness where applicable | Processor record and the tests required by your drawing |
For your bores, threads and press fits: state whether dimensions apply before or after finishing. Coating growth is process-dependent; agree allowances with the processor rather than assuming one fixed ratio.
Choose a Resin Grade, Not Just “Fire-Retardant Plastic”
Specify the recognized grade, tested thickness and color for your enclosure.
UL 94 HB
Horizontal burning classification. It is not equivalent to a vertical V rating.
UL 94 V-2 · V-1 · V-0
Vertical classifications consider extinguishing time and flaming drips. Request the exact rating at your specified thickness.
UL 94 5VB · 5VA
More severe flame exposure. Do not substitute ratings across test methods or assume whole-product certification.
| Published grade example | Test thickness | UL 94 classification |
|---|---|---|
| Covestro Bayblend FR3010 · PC/ABS | 1.5 mm | V-0 |
| Same named grade | 2.0 mm | 5VB |
| Same named grade | 3.0 mm | 5VA |
Manufacturer-published grade example only—not a stocked-resin promise or certification of your part. Confirm the current recognition, approved color and thickness; different test methods are not interchangeable.
Your resin requirement: manufacturer + exact grade + reinforcement + color + minimum wall thickness + UL recognition record. An ABS, PC/ABS or PA family name does not guarantee V-0. UL 94 is a small-scale material flammability classification, not a “fireproof” claim.
Agree Your Report Package Before Production
Tell us which records your buyer requires. Availability, scope, timing and any testing cost must be confirmed in the quotation.
FAI / FAIR
First-article dimensional results against the controlled drawing, revision and numbered characteristics. Request AS9102 format only when contractually required and agreed.
CoC / Certificate of Conformity
Identify the part, revision, order and delivered lot, with an authorized conformity statement. A CoC does not replace measured results or material test data.
MTR / Material Certificate
Material grade, condition, heat/lot traceability and the chemistry/mechanical results required by the order. State EN 10204 3.1 explicitly if needed.
Finish & Test Records
Process specification/revision, processor and batch, with thickness, hardness or other results only for the agreed tests and locations.
PPAP Package
Agree the customer-specific submission level, elements and PSW before the production run. The package may include process flow, PFMEA, control plan, MSA and capability studies as required.
Resin & Lot Traceability
Confirm the resin grade, color, lot record and applicable UL recognition. A supplier datasheet is not a test report for your molded part.
FAI, CoC, material certificates and PPAP serve different purposes. This is a requirements menu, not a claim that every package is included or every program is approved. Customer approval and acceptance remain separate steps.
Keep Process Standards and Company Certification Separate
Use the exact designation and revision required by your contract.
| Reference | What it addresses | Confirm for your project |
|---|---|---|
| MIL-PRF-8625 | Anodic coatings on aluminum; formerly MIL-A-8625 | Type, class, thickness, sealing and testing |
| MIL-DTL-5541 | Aluminum chemical conversion coatings | Type I / II, Class 1A / 3 and electrical/corrosion requirements |
| ISO 7599 / ISO 10074 | Decorative/protective anodizing / hard anodizing | Applicable standard, revision and acceptance criteria |
| ISO 9001 | Quality management system requirements | Current certificate, legal entity, site, scope, issuer and validity |
| AS9102 / AIAG PPAP | FAI documentation / production part approval process | Customer-required format, submission scope and sign-off |
These are references for specifying your order, not certification badges. ISO 9001 concerns a management system; it does not certify an individual part. No AS9100, IATF 16949, UL or military qualification is implied by this table.

BEFORE YOUR FIRST ORDER
Frequently Asked Questions
Can you work alongside our existing supplier?
Yes. Start with a selected part or overflow requirement. Your qualification process determines whether LK MFG becomes an approved second source.
What are the typical sample and production lead times?
Timing depends on geometry, quantity, material, tooling and inspection. Send these inputs so your quotation can separate sample, tooling and production milestones.
Can you test threads and assembly fit?
Request thread gauge and mating-part checks in your drawing or RFQ. We confirm the method, scope and required sample hardware before production.
Can you hold inventory in Texas and ship smaller quantities?
Discuss an agreed inventory program, including stock ownership, replenishment, release quantities and delivery addresses. Availability is project-specific.
How do you handle powder-coat color consistency?
Define a physical approved sample, gloss, texture, masking and acceptance criteria. Review coating allowance on threads and mating surfaces.
How are import duties and landed costs handled?
Confirm the quotation’s trade terms, importer responsibilities, freight and duty assumptions. Tariffs depend on classification, origin and current rules; no fixed duty rate is promised.
Can you provide DFM review with specific suggestions?
Send a controlled drawing and CAD file. Review can cover tool access, wall thickness, threads, tolerances and process alternatives for your part.
What payment terms are available?
Terms are confirmed in your quotation and order agreement. Ask about tooling, sample and production payment milestones before placing an order.
