We specialize in crafting client-customized molds for tablet middle frames—tailored for tablet OEM/ODM manufacturers, consumer electronics brands, and custom device suppliers. Every mold is engineered to 1:1 match your 2D/3D files (CAD, STEP, IGES, DXF), whether your middle frame design is for 10.9-inch education tablets, 12.9-inch business models, or foldable tablet variants. As the "connecting core" of tablets (linking screen, back cover, and internal components like motherboards), our middle frame molds prioritize three key needs: ultra-precise alignment, long-term durability, and scratch-resistant 外观 (appearance)—all delivered via ±0.005mm tolerance, H13 steel, and anti-scratch finish.
Why Our Tablet Middle Frame Molds Fit Your Production
Tablet middle frames have strict requirements that generic molds often fail to meet—our design targets the practical challenges you face in manufacturing:
Misalignment Ruins Assembly Efficiency: Middle frames need to align with screen edges, back cover grooves, and screw holes (for fixing internal parts). Even 0.01mm deviation causes "screen bulging" or "back cover gaps," forcing 12%+ assembly rework and slowing down production lines;
Daily Wear Damages Frame Appearance: Tablets are frequently placed on desks or carried in bags—middle frames with poor surface resistance get scratched easily, leading to 8%+ end-product returns. Our anti-scratch finish solves this for consumer-facing designs;
Frequent Production Wears Out Molds: Popular tablet models require 150k+ middle frame units per run. Standard steel molds wear out after 80k cycles, but H13 steel ensures our molds keep up with high-volume demands without precision drift.
Core Strengths for Middle Frame Manufacturing
1. Full Compatibility with Your 2D/3D Files
We accept all mainstream design formats—from 2D DXF/PDF (for basic frame outlines) to 3D CAD/STEP (for complex structures like port cutouts, speaker grilles, or hidden 卡扣 (clips)). Our team first reviews your files to optimize manufacturability: for example, adjusting the draft angle of screw holes to avoid resin buildup, or refining speaker grille spacing to prevent blockages. No more "design vs. mold mismatch"—every detail of your middle frame is replicated exactly.
2. ±0.005mm Tolerance for Seamless Assembly
Middle frames are the "bridge" between tablet components, so precision in key areas is non-negotiable. Our molds maintain ±0.005mm tolerance for:
Frame edges (to fit screen and back cover without gaps);
Screw holes (to align with internal brackets, avoiding "stripped screws");
Port cutouts (USB-C, headphone jacks—ensuring no interference with plug-in use). This precision cuts assembly time by 15% and eliminates fit-related scrap.
3. H13 Steel for Durable Molds & Consistent Output
We use H13 steel (52–54 HRC hardness) for two critical benefits:
Mold longevity: Handles 200k+ production cycles—2.5x longer than standard steel. This means one mold can cover most high-volume runs (e.g., 150k middle frames for a popular tablet model) without replacement;
Stable precision: Resists wear from repeated injection, so the 100th middle frame has the same dimensions as the 10,000th—no "late-cycle deviation" that ruins batch quality.
4. Anti-Scratch Finish for Consumer-Ready Quality
Our molds are treated to create a smooth, anti-scratch surface on middle frames (Ra ≤0.01μm roughness). This means:
No easily visible scratches from daily use (e.g., placing the tablet on a wooden desk);
Reduced need for post-production polishing (saving 5% of manufacturing costs);
A premium look that meets consumer expectations for tablet aesthetics.

Quality You Can Rely On
Our mold production follows a standardized workflow: we test H13 steel hardness before machining, use Zeiss CMM tools to verify ±0.005mm tolerance, and run 50+ test injections with your target resin to check frame fit and finish. We also provide traceable records—material certificates, inspection logs—to help you track supply chain quality without extra effort.
Who We Partner With
Tablet OEM/ODM Manufacturers: For mass-producing middle frames for standard tablet lines, where H13 steel durability and ±0.005mm precision support efficient assembly;
Consumer Electronics Brands: For launching custom tablet models (e.g., branded business tablets, rugged outdoor tablets), where anti-scratch finish and 1:1 design alignment preserve brand aesthetics;
Custom Device Suppliers: For niche tablets (e.g., industrial control tablets, medical-grade devices), where H13 steel’s durability stands up to frequent production runs of specialized middle frames.
Let’s Bring Your Middle Frame Design to Life
If you have a 2D/3D file for your tablet middle frame, upload it to our platform—our engineers will send a free DFM (Design for Manufacturability) report (with tips to optimize screw hole layout, port cutouts, or finish) and a detailed quote within 24 hours. We’ll adjust any details to ensure the mold fits your production goals.
