German HAZET tools HAZET models HAZET prices

HAZET tools refer to the general term for various metal devices manufactured through physical processing such as forging, rolling, and cutting of metals like iron, steel, and aluminum. Hardware tools, classified by product application, include: tool hardware, construction hardware, daily-use hardware, locks and abrasives, kitchen and bathroom hardware, home hardware, and hardware components. These include various manual, electric, pneumatic, and cutting tools; automotive maintenance tools; agricultural tools; lifting tools; measuring tools; tool machinery; cutting tools; jigs and fixtures; cutters; molds; cutting edges; grinding wheels; drill bits; polishing machines; tool accessories; measuring and cutting tools; painting tools; abrasives and grinding materials; manual socket wrench sockets; striking open-end wrenches; and striking box-end wrenches.

HAZET tool features

1) Air is easily accessible, operates at low pressure, and used air can be discharged locally without requiring recovery pipelines. 2) Air has low viscosity and minimal flow resistance loss, facilitating centralized air supply and long-distance transmission. 3) Pneumatic actuators offer high movement speeds. 4) Pneumatic systems have strong environmental adaptability, operating reliably in wide temperature ranges, humid, and dusty conditions. Minor leaks do not pollute the environment, there is no risk of fire or explosion, ensuring safe usage. 5) Simple structure, easy maintenance, and low cost. 6) Long service life of pneumatic components. 7) Pneumatic components have lower output force compared to hydraulic systems but offer faster motion, strong adaptability, and can operate in harsh environments such as flammable, explosive, dusty, humid, and impact-prone areas. They do not pollute the environment, have a long service life, simple construction, easy maintenance, and low price.

HAZET tool classification

Non-sparking tools are internationally known as "safety tools" and "non-sparking tools," and domestically referred to as "explosion-proof tools." In China, explosion-proof tools produced, sold, and distributed are categorized into two main types based on material: 1. Aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools, made from high-purity electrolytic copper with added aluminum, nickel, manganese, iron, and other metals to form a copper-based alloy. 2. Beryllium-copper alloy (commonly known as beryllium bronze) explosion-proof tools, made from high-purity electrolytic copper with added beryllium, nickel, and other metals to form a copper-based alloy. Both materials exhibit excellent thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are comparable to beryllium bronze, both reaching above HRC30o. Beryllium bronze is non-magnetic and suitable for strong magnetic field environments. Explosion-proof tools are also categorized into two main types based on manufacturing process: 1. Casting process: A traditional manufacturing method widely used internationally in the 80s and still employed by most domestic explosion-proof tool manufacturers. Advantages: Simple process and low manufacturing cost. Disadvantages: Lower product density, hardness, tensile strength, and torque; numerous pores and sand holes result in shorter product service life. 2. Forging process: The latest international manufacturing technique, using large presses or punch machines with high-heat-resistant forming molds for single-step forging. Advantages: Significantly improves product density, hardness, tensile strength, and torque; virtually eliminates pores and sand holes, extending mechanical performance and service life by approximately 1 times compared to traditional casting. Disadvantages: High investment in equipment and molds leads to higher costs.

HAZET tool usage

1) Explosion-proof tools provide safety assurance for personnel working in flammable, explosive, and corrosive environments, enhancing social safety and allowing workers to operate with greater confidence. After daily use, proper maintenance is crucial for tool longevity; improper maintenance may prevent tools from serving effectively over time. First, store tools in a dry place to protect working parts from damage. After continuous striking 20 times during daily work, surface attachments should be cleaned off before reuse. Avoid continuous use to prevent overheating due to prolonged friction, which could damage the tool. 2) After use, wipe clean surface dirt and deposits, and store in a dry, safe location. 3) Striking tools must not be used continuously; allow appropriate intervals after ten strikes, and promptly remove debris adhering to the tool before continuing use. 4) Wrenches must not be used with excessive force. Do not extend leverage by attaching sleeves or binding other metal rods, and do not strike with a hammer (except for striking wrenches) to tighten fasteners. 5) Cutting-edge tools should be gently ground against a grinding wheel in a water trough; avoid excessive force or prolonged contact with the wheel. 6) During actual operation of chiseling and striking tools, clear site debris and corrosive oxides from the work surface to prevent third-party impacts. Based on these characteristics and usage, aluminum-copper alloys are more suitable for normal-pressure equipment and environments with less stringent explosion-proof requirements (e.g., gas stations, small oil depots). Beryllium-copper alloy explosion-proof tools are suitable for demanding environments (e.g., refineries, gas transfer stations, gas extraction plants, drilling teams). 7) Remove surface oil stains before using any product, and follow the instructions for steel tools.
