Product Description
High-Resolution Electroformed Molds For Microfluidic Diagnostic Chips – Tolerance ±0.002mm, Compatible With PDMS/Glass Substrates
Precision Electroformed Molds for Microfluidic Diagnostic Chips
Engineered for IVD (In Vitro Diagnostic) manufacturers, POC (Point-of-Care) device developers, and clinical diagnostic labs, our high-resolution electroformed molds are purpose-built to produce microfluidic diagnostic chips—from rapid antigen test chips to nucleic acid amplification (PCR) chips. With ultra-tight ±0.002mm tolerance and optimized compatibility with PDMS (polydimethylsiloxane) and glass substrates, they ensure precise replication of micro-channels (10-300μm width/depth) and functional structures (reaction chambers, valve seats), directly supporting accurate, repeatable diagnostic results.
Why Our High-Resolution Electroformed Molds Stand Out
Microfluidic diagnostic chips demand molds that solve 3 critical pain points ordinary molds fail to address:
- Tolerance Gaps Ruin Detection Accuracy: Generic molds with ≥0.005mm tolerance create inconsistent micro-channel dimensions, leading to uneven fluid flow (e.g., delayed sample mixing in PCR chips) and false positive/negative results.
- Substrate Incompatibility Causes Chip Scrap: Poorly optimized molds struggle with PDMS (sticky, high-shrinkage) or glass (brittle, tight bonding requirements), resulting in 15-20% chip scrap rate during demolding or bonding.
- Low Resolution Loses Functional Details: Diagnostic chips rely on tiny structures (e.g., 50μm-wide reagent reservoirs, 20μm-thin valve gaps) that standard molds can't replicate, rendering chips non-functional.
Our solution combines high-resolution electroforming technology with substrate-specific design—turning diagnostic chip production from a "risky process" into a reliable, scalable workflow.
Core Customization Capabilities for Diagnostic Chip Molds
We tailor every mold to your diagnostic chip's unique microfluidic design and substrate needs, with flexibility to handle even complex functional structures:
| Customization Dimension | Key Options | Our Advantage |
|---|---|---|
| Micro-Structure Replication | Micro-channels (10-300μm width/depth), reaction chambers (0.1-5mm volume), valve seats (20-100μm gap), reagent reservoirs (0.5-10μL capacity) | Electroforming captures nanoscale details—ensures every structure's dimension deviates ≤±0.002mm, critical for consistent fluid dynamics in diagnostic assays |
| PDMS/Glass Substrate Optimization | PDMS-specific: Mold surface treatment (anti-adhesion coating) to reduce demolding force; Glass-specific: Alignment notches for precise chip bonding | Cuts PDMS chip scrap rate by 35% (no tearing during demolding) and ensures glass chip bonding accuracy (≤0.003mm offset), avoiding leaky channels |
| Client Drawing Support | 2D (DXF/PDF) & 3D (CAD/STEP/IGES) files; supports layout designs (serpentine channels for PCR, parallel channels for multi-assay chips) | Free pre-production DFM (Design for Manufacturability) analysis to optimize structure connectivity (e.g., eliminating dead zones in reaction chambers); 100% drawing alignment guaranteed |
| Diagnostic-Specific Enhancements | Integrated air vent micro-holes (prevents bubble trapping in samples), temperature control grooves (for PCR thermal cycling), barcode/marking structures (chip traceability) | Solves diagnostic workflow pain points—e.g., air vents reduce assay failure rate by 25% in rapid antigen test chips |
Technical Specifications: Built for Accurate, Scalable Diagnostic Chip Production
Our molds are engineered to meet the strict standards of clinical diagnostics, with specs that directly impact chip performance and assay reliability:
| Specification | Standard for Diagnostic Chip Molds | Impact on Your Diagnostic Chip Production |
|---|---|---|
| Dimensional Tolerance | ±0.002mm (micro-channels, reservoirs, valve seats) | Ensures consistent fluid flow and reagent mixing—critical for repeatable diagnostic results (e.g., CV ≤5% in nucleic acid detection) |
| Surface Roughness | Ra ≤0.03μm (micro-channel walls) | Minimizes fluid friction and sample adsorption (e.g., no protein sticking to channel walls), preserving sample integrity |
| Substrate Compatibility | Optimized for PDMS (Sylgard 184), borosilicate glass, soda-lime glass | Supports most common diagnostic chip substrates—no need to switch molds for different substrate types |
| Service Life | ≥40,000 replication cycles (nickel alloy); ≥60,000 cycles (nickel-copper alloy) | Sustains mid-to-high volume production (e.g., 500,000+ rapid test chips/year) without mold wear or precision drift |
| Lead Time | 16-22 days (prototype); 25-32 days (mass-production) | Faster than industry average (35+ days) to accelerate diagnostic chip R&D and market launch (critical for emerging pathogens like new flu strains) |
Quality & Compliance for Clinical Diagnostics
- Medical-Grade Certifications: Molds meet ISO 13485 (Medical Device Quality Management System) standards—critical for IVD products requiring regulatory approval (FDA 510(k), CE IVDR).
- Biocompatibility Assurance: Electroforming materials (99.95% pure nickel, nickel-copper alloy) pass ISO 10993-5 (cytotoxicity) and ISO 10993-10 (irritation) tests—no leachable contaminants to compromise biological samples (blood, saliva, cells).
- Cleanroom Manufacturing: Molds are produced in a Class 1000 cleanroom (ISO 14644-1) to avoid dust/particle contamination—essential for diagnostic chips where even 1μm particles can block micro-channels or interfere with assays.
- Traceability: Full batch records (material certificates, dimensional inspection reports, cleanroom monitoring data) are provided—supporting regulatory audits (e.g., FDA inspections) for IVD products.
Who Benefits from Our Diagnostic Chip Molds
- IVD Manufacturers: For high-volume production of rapid diagnostic chips (e.g., COVID-19, flu, malaria tests) where ±0.002mm tolerance ensures consistent assay performance.
- POC Device Developers: For compact diagnostic chips (e.g., handheld blood glucose monitors, on-site pathogen detectors) requiring small, precise micro-structures and PDMS/glass compatibility.
- Clinical Research Labs: For custom diagnostic chips (e.g., personalized cancer biomarker tests) with unique microfluidic layouts—our DFM support accelerates prototype iteration.
