INJECTION MOLDING
Plastic enclosure and molding specifications
Aluminum rapid tooling for prototype stage, P20 and H13 steel for production. All tooling is client-owned from the moment it is paid for. Tolerances and material properties below are for standard commercial enclosure applications.
Tooling options and key specifications
Multi-cavity tooling (2, 4, or 8+ cavities) reduces per-part cost at higher production volumes by producing multiple parts per machine cycle. Cavity count decision depends on annual production volume, part complexity, and tooling budget. Multi-cavity tooling is designed and quoted on a per-project basis.

IP68 design available on request. Tested IP rating certification support (producing test samples) is available for FCC/CE-registered test labs.
METAL FABRICATION
Metal parts and enclosure specifications
Three metal fabrication processes — sheet metal, CNC machining, and die casting — each with different tolerance capabilities, volume economics, and design requirements. Prototypes from 1 piece across all metal processes.
Sheet Metal
Enclosure panels, brackets, chassis, and structural parts. Flat-to-3D geometry using cutting and bending. Best for thin-wall parts (0.5–3mm) requiring consistent geometry and surface area.
Volume economics:
Prototypes from 1 piece. Production from 10+ pieces. Cost per part decreases with quantity but not dramatically — no tooling amortization barrier.
Laser cut Bend Weld Hardware
SHEET METAL SPECIFICATIONS
Minimum sheet thickness: 0.5mm
Maximum sheet thickness: 6mm (standard), 12mm (special request)
Maximum sheet size: 2,000mm × 1,000mm
Minimum bend radius: 0.5× material thickness
Minimum flange height: 3× material thickness
Minimum hole diameter: Equal to material thickness
Minimum hole-to-edge: 2× material thickness
Laser cut tolerance: ±0.1mm
Formed dimension tolerance: ±0.2mm
Angular tolerance: ±0.5° per bend
Maximum part size (formed): 1,200mm × 600mm × 500mm
Welding: TIG, MIG, spot — all available
Hardware insertion: PEM nuts, standoffs, studs — all available
Minimum prototype quantity: 1 piece
Standard production MOQ: 10 pieces
Precision parts requiring tight tolerances, complex 3D geometry, or material properties unavailable in sheet metal. Housings, heatsinks, brackets with machined features, custom mechanical interfaces.
Volume economics:
Prototypes from 1 piece. Economical at 1–500 pieces. Unit cost decreases slowly with volume — no step-change. High per-unit cost at very high volumes (die casting typically preferred above 1,000+ complex parts).
3-axis 5-axis Turning Precision
SHEET METAL SPECIFICATIONS

Precision tolerance: ±0.010mm
Flatness: ±0.02mm/100mm
Parallelism: ±0.02mm
Perpendicularity: ±0.05mm
Surface roughness — standard: Ra 1.6µm
Surface roughness — fine: Ra 0.8µm
Axis capability: 3-axis standard, 5-axis available
Turning/lathe: Yes — cylindrical parts/features
Thread tapping: Yes — metric and imperial
Minimum prototype quantity: 1 piece
Standard production MOQ: 1 piece (no MOQ)
Typical lead time — prototype: 5–7 days
Typical lead time — production: 10–15 days
CNC Machining
High-volume metal parts requiring complex geometry with consistent wall thickness — aluminum or zinc alloy housing shells, connector bodies, structural components. Combines injection-molding-like complexity with metal properties.
Volume economics:
Tooling required (higher one-time cost than injection mold). Economical above 1,000–2,000 pieces. Unit cost well below CNC at high volume. Not suitable for low-volume or prototype applications.

Draft angle: 1–2° internal, 0.5–1° external
Post-machining: Available — for tight-tolerance
Minimum production quantity: 1,000 pieces
Tooling cost range: $5,000–$25,000 per cavity
Tooling lead time: 4–6 weeks
Unit cost range: Varies significantly by complexity — quoted per project
Die Casting
COMPONENT SOURCING
Sourcing and supply chain capabilities
Authorized distributors only — no open market, no grey market, no exceptions. BOM management from initial quote through ongoing production cycles, with continuous lead time monitoring and supply risk alerting.
Authorized distributors only - every BOM line
Every component in every BOM is sourced from authorized distributors in the franchised distribution chain. Peakingtech does not purchase from broker networks, trading companies, or spot market platforms regardless of pricing or availability pressure. When authorized stock is unavailable at acceptable lead time, the response is alternative component qualification — not open market sourcing.
DISTRIBUTOR NETWORK
PRIMARY AUTHORIZED DISTRIBUTORS
Digi-key
Mouser Electronics
Arrow Electronics
Avent
Future Electronics
RS Components
Certificate of conformance required from all suppliers for ICs and active components. Documentation retained and available to client on request.
INCOMING INSPECTION PROTOCOL
Certificate of conformance verification
Lot code and date code recording
Visual inspection
Physical verification
Functional spot-check
Counterfeit electronic components — particularly integrated circuits — are a real and persistent supply chain risk that has affected products from every tier of the electronics industry. The risk is highest for components sourced outside the authorized distribution chain, which is why Peakingtech's no-open-market policy is the most important single counterfeit prevention measure. For authorized distributor stock, the incoming inspection protocol provides a second verification layer.
Multi-layer counterfeit detection at incoming inspection
COUNTERFEIT PREVENTION
SERVICES INCLUDED
Initial BOM sourcing: Full BOM quoted from Gerber/BOM files
Lead time analysis: Line-by-line lead time analysis at each production cycle
Alternative qualification: Authorized alternates qualified for single-source components and long-lead risk mitigation
BOM cost optimization: Volume pricing evaluation, alternative component evaluation for cost reduction
Discontinuation monitoring: Active monitoring for EOL (end-of-life) and NRND (not recommended for new designs) notices
Last-time buy coordination: Coordination of last-time buy quantities for discontinued components
BOM revision management: Design change order support — revised BOM managed per engineering change order
Cross-reference: Cross-reference to verified alternatives for obsolete or unavailable components
BOM management covers the complete component supply lifecycle — from initial BOM review against design files through ongoing availability and pricing monitoring across production cycles. The service is integrated with the production planning cycle rather than treated as a one-time procurement activity.
Complete BOM management from design through ongoing production
BOM MANAGEMENT
ONGOING ACTIVITIES
Lead time monitoring: Component lead time changes monitored continuously. Client alerted when lead time increase affects production schedule or reorder point calculation.
Safety stock planning: Reorder parameters — MOQ, safety stock, reorder point — established at production start and updated as actual demand data replaces forecast.
Supply risk alerting: Single-source components, allocation notices, and supply disruption signals monitored. Alternative qualification initiated proactively when risk is identified.
Supply chain event log: Any supply chain event — price spike, allocation, lead time change, quality incident — documented and shared with client. Builds supply chain intelligence across production cycles.
Ongoing supply chain management is the difference between a manufacturing partner and a manufacturing service. A service executes production orders. A partner monitors the supply chain between orders, alerts to risks before they become crises, and adjusts reorder parameters as demand patterns evolve.
