Injection Molding
Tooling and molding for your repeat plastic parts.
YOUR PART. YOUR REVIEW QUESTION. YOUR EVIDENCE.
Manufacturing Application Examples Connect Your Part Features to the Decisions Behind Production
Explore enclosure, machining and prototype planning examples. Compare the drawing, process and acceptance questions your team should resolve before using another project as a reference.
These are illustrative engineering scenarios, not LK MFG customer case studies or verified savings and test results.
What Your Custom Enclosure Example Should Explain
Start with the interfaces
Identify board mounts, connectors, access openings, mating cover and installation envelope.
Compare manufacturing routes
Review geometry, quantity, material, finish and assembly before choosing machining, forming or another route.
Define the acceptance
Agree critical dimensions, contact areas, appearance and required records.
A custom enclosure manufacturing case study is useful when its requirements and evidence are comparable to yours. A photograph alone does not establish suitability.

Use DFM Before and After Examples to Ask Better Questions
Compare the proposed geometry change with the function it must preserve. These two concepts illustrate different tool access; they are not a documented redesign or approved interchangeable parts.
Explain the proposal
Identify which pocket, corner, wall, hole or setup would change and why it needs review.
Protect the function
Review mating parts, loads, clearance and critical drawing requirements before approving a change.
Keep the record
Agree the revised drawing and required sample evidence. Do not accept an undocumented adjustment as the production baseline.
Separate Prototype Evidence from Repeat-Supply Evidence
When reading a prototype to production case study, ask which material, geometry, process and acceptance conditions changed between stages.
Prototype question
What did the sample demonstrate: appearance, fit, a specific function or another agreed requirement?
Production baseline
Which drawing, process, material and checks were approved for repeat supply?
Handoff evidence
Which records, packing requirements and change approvals carry forward to the next order?
Compare the Assumptions Behind a Cost-Reduction Claim
Illustrative total-cost comparison
Assume Route A has setup 100 and unit cost 8; Route B has setup 500 and unit cost 4. All values are hypothetical cost units, not USD, quotes or LK MFG prices.
10 parts
Route A: 180Route B: 540
100 parts
Route A: 900Route B: 900
200 parts
Route A: 1700Route B: 1300
Total = setup + quantity × unit cost. At 100 parts both routes equal 900 units; at 200 parts A = 1,700 and B = 1,300. Horizontal scale starts at 0 and ends at 1,700 units. No actual savings are claimed.
What should a manufacturing case study demonstrate?
A CNC machining case study cost reduction claim needs a defined baseline, approved changes, quantity, comparable material/finish/acceptance and actual commercial evidence. This simplified arithmetic excludes inspection, tooling life, scrap, packing, freight, taxes, lead time and other costs. Compare complete quotes for your real scope.
6 Inputs for Your Application Review
- CAD and controlled drawing revision.
- Part function, mating components and critical interfaces.
- Full material and finish requirements.
- Trial quantity and expected repeat demand.
- Required checks, records and approval responsibility.
- Packing, delivery and any proposed design alternatives.
Answers Before You Use an Example
Are these actual LK MFG customer projects?
No. The scenarios and component images are illustrative. They do not document customer parts, measured results or commercial savings.
Can a similar-looking part use the same process?
Not automatically. Compare geometry, material, quantity, function and acceptance requirements for your own drawing.
Can DFM changes be made without approval?
Identify proposed deviations and obtain the required approval before using a revised baseline. Keep drawing and sample records aligned.
Does the cost example tell me which route is cheaper?
Only under its disclosed hypothetical assumptions. Your complete quotation and required production scope determine the actual comparison.
