KHT MLB-01 Digital Falling Dart Impact Tester

Film Toughness Analysis • Method A & B • ASTM D1709 / ISO 7765-1

Stop packaging failure before it happens. The MLB-01 determines the 50% Impact Failure Mass using an intelligent Staircase Method workflow. It features pneumatic clamping, an interference-free 3-jaw pneumatic gripper release, and dual-mode (0.66 m / 1.50 m) testing capability for ASTM D1709 and ISO 7765-1 compliance.

Dual Methods

Integrated Method A (0.66 m) & Method B (1.50 m) in one unit

Smart Algorithm

Auto-calculates 50% Failure Mass (Staircase Method)

Solid Stability

20 mm solid aluminum base ensures vibration-free impact

Zero Magnetism

3-jaw pneumatic release prevents dart sticking (no residual magnetism)

Industry-Specific Applications

Versatile Solutions

From safeguarding pharmaceutical sterility to ensuring heavy-duty industrial film durability, the MLB-01 delivers standards-based impact analysis across critical sectors.

Food & Flexible Packaging

Food & Flexible Packaging

Prevent bag bursts and transport damage. The MLB-01 accurately measures the impact resistance of composite films used in frozen food, snacks, and liquid pouches, following ASTM D1709 Method A and GB/T 9639.1 for films up to 1 mm.

Pharma & Medical Packaging

Pharma & Medical Packaging

Critical for IV infusion bags, dialysis bags, and pharmaceutical laminated films. Supports impact testing of flexible composite films defined in YBB 00132002 using the ASTM D1709 / ISO 7765-1 free-falling dart method, helping ensure that soft medical packaging withstands handling shocks without leakage.

Logistics & Stretch Wrap

Logistics & Stretch Wrap

Solve pallet wrapping failures before they reach the warehouse floor. Using the high-energy Method B (1.50 m drop with heavier darts), the MLB-01 evaluates the puncture resistance of stretch wraps and heavy-duty shipping sacks against sharp corners, pallets, and forklifts within the film thickness range defined by the standards.

Agriculture & Greenhouse Films

Agriculture & Greenhouse Films

Assess the durability of greenhouse covers and mulch films against hazards like handling damage and hail impact. The Staircase Method allows R&D teams to compare resin formulations and structures for thinner yet tougher films within the applicable thickness scope of ASTM D1709 and ISO 7765-1.

Product Overview

Lab-Grade Precision

Eliminate human error and magnetic interference. Unlike testers that rely on electromagnets, the MLB-01 uses a precision 3-jaw pneumatic gripper to ensure clean, repeatable release for both light (50 g) and heavy (up to 2000 g) darts.

R&D & Method Expertise

R&D & Method Expertise

Our dedicated R&D team implements the core staircase algorithm used to determine 50% failure mass (M50) in line with ISO 7765-1 and ASTM D1709, rather than simply assembling generic control boards.

Weight Calibration

Weight Calibration

Accuracy is non-negotiable. Every dart body and increment weight (5 g, 15 g, 30 g, 60 g, 45 g, 90 g, etc.) is calibrated on high-precision balances to stay within tight tolerances consistent with the accuracy requirements of ASTM D1709.

Pneumatic Engineering

Pneumatic Engineering

We replaced the problematic electromagnet concept with a 3-jaw centering pneumatic cylinder. This design eliminates residual magnetism and allows even the lightest 50 g darts to fall freely without sticking.

72-Hour Aging Test

72-Hour Aging Test

All control boards and pneumatic release mechanisms undergo a continuous 72-hour aging test to verify stability under high-repetition operating conditions, reducing the risk of early-life failures.

Rigorous Quality Control

Rigorous Quality Control

Our QC protocol includes a drop verticality check to ensure the dart hits the exact center of the sample, along with regular verification of clamp pressure and height setting accuracy.

Solid Foundation

Solid Foundation

Accuracy starts at the base. We machine a 20 mm thick solid aluminum alloy plate that sits directly on your lab bench. Unlike suspended chassis designs, this structure minimizes vibration and resonance during high-energy impacts.

Real-World Success Stories

Proven Results

Discover how industry leaders use the MLB-01 to solve critical packaging failures.

Frozen Food Processor (Thailand)

Frozen Food Processor (Thailand)

A producer of frozen peas faced high bag breakage rates during cold-chain transport. Using the MLB-01 and Method A with low-temperature conditioning, they identified that their film became brittle at −20 °C. By adjusting the resin blend and verifying with impact testing, they reduced breakage by around 80%.

Pharma IV Bag Manufacturer (India)

Pharma IV Bag Manufacturer (India)

A saline bag supplier needed impact data aligned with YBB and ISO requirements for export to Europe. Their manual tester showed high variability. The MLB-01’s pneumatic clamping and automated staircase calculation provided consistent results, helping them pass a rigorous client audit.

Logistics Center (USA)

Logistics Center (USA)

A logistics hub wanted to benchmark the puncture resistance of inbound pallet wraps from different suppliers. With the MLB-01 set up for Method B (1.50 m), they created a clear ranking and selected the most cost-effective film that still met their damage thresholds.

QA Lead | FlexPack Solutions

We used to calculate the staircase method manually in Excel. It was slow and error-prone. The MLB-01 does the calculation automatically and prints a result ticket for every batch. It easily saves our technicians about an hour per day.

Lab Director | Bio-Films Tech

The dual-mode capability is fantastic. We test thin biodegradable films with Method A and thicker mulching films with Method B on the same machine. It’s a true space saver and very intuitive for our team.

Production Manager | AgroPlast

The pneumatic clamping is the real game-changer. Our old manual rig always had slippage and off-center hits. The MLB-01 holds the sample rock-solid and keeps the dart centered, even for slippery PE films.
