KHT is a source manufacturer of advanced material testing instruments. Specializing in Falling Dart Impact Testers, we help the global pharmaceutical, food, and flexible packaging industries validate compliance with ASTM D1709, ISO 7765-1, and GB/T 9639.1 standards.
KHT (Key High Tech) is a specialized high-tech enterprise focused on the mechanics of material failure and the manufacturing of precision test hardware. Unlike general trading companies, we are a true source manufacturer with independent intellectual property. From 20 mm solid aluminum bases to innovative 3-jaw pneumatic gripper release mechanisms, we control every critical component to ensure your lab obtains reliable, interference-free impact data.
Our instruments serve critical sectors including national quality inspection centers, pharmaceutical R&D labs, and flexible packaging producers. Whether it is determining the impact failure mass of IV bag films, testing Tyvek-based medical packaging, or validating the toughness of heavy-duty shipping sacks, KHT’s MLB series testers apply the staircase method to deliver intelligent, automated results that minimize operator influence.
Driven by the philosophy of 'Precision First, Reputation Long-Term', KHT has built an integrated R&D and service team. We go beyond selling hardware by offering solutions aligned with global standards (ASTM, ISO, JIS, GB/T), helping our partners’ materials perform safely and consistently throughout the international supply chain.
To safeguard product integrity by delivering highly accurate falling dart impact testers that reduce packaging failure in pharmaceutical and food supply chains.
To become a trusted global reference in material impact testing, continuously refining our Method A & B dual-mode technology to meet the increasing stringency of pharmacopoeia and international safety requirements.
Scientific rigor, user-centric design, and global compliance. We uphold a 'boutique manufacturing' mindset, ensuring every KHT instrument passes strict QC verification before leaving our factory.
✔ Factory-Direct Value: As the original manufacturer, KHT removes middleman markups and delivers premium hardware—such as pneumatic clamping and 8-inch touch screens—at a competitive, transparent price level.
✔ Method A & B Expertise: Our systems are engineered to handle both low-energy (0.66 m) and high-energy (1.50 m) free-falling dart tests, covering a wide range of standard film thicknesses from food packaging films to more robust industrial laminates.
✔ Standards-Ready Design: KHT impact testers are configured to support the core free-falling dart standards used worldwide, including ASTM D1709, ISO 7765-1, JIS K7124-1, and GB/T 9639.1, giving you confidence in audits and customer evaluations.
✔ Long-Term Technical Support: We back our instruments with a solid warranty and provide ongoing remote technical support for both software and hardware questions throughout the life of the tester.
Powered by an independently developed control board and an 8-inch color touch screen, the MLB series offers precise data acquisition and guided workflows beyond what basic industrial PLC-based solutions typically provide.
Each tester features a 20 mm solid aluminum base for vibration-resistant stability and a 3-jaw pneumatic gripper for dart holding and release. This architecture eliminates the residual magnetism issues common in electromagnetic testers and ensures clean drops for both 50 g and 2 kg dart assemblies.
KHT provides impact testing solutions for PE-based films, pharmaceutical laminated films for IV bags and drug sachets, medical packaging materials such as Tyvek laminates, and emerging biodegradable films—always with a focus on real-world logistics and handling conditions.
With Chinese/English dual-language interfaces and dedicated overseas support, KHT offers export-ready instruments. From installation guidance to daily operation training, we support global labs and factories throughout the full life cycle of the equipment.
