German HALDER standardized industrial components, more than 13000 kinds of product lines can meet the application needs of various industrial occasions. At the same time, the diversity, innovation and high quality of products contribute to the convenience and stability of customers in the stage of product design and development. HALDER products are invisible but ubiquitous.

German HALDER soft hammer was born in 1938, which is the first professional hand tool made of non-metallic materials in the world. At the same time, the design concept of unique replaceable parts has also been patented in Germany. Today, HALDER soft hammer has developed a variety of materials and series of hammers for a variety of occasions and application scenarios, from high-end manufacturing to landscape engineering; from equipment maintenance to personal collection. HALDER Soft Face Hammer is the absolute leader in the field. It has a very wide range of users and advocates around the world. Small hammer, big difference "HALDER soft hammer will give you a unique use experience.".

HALDER Aviation Latches are aviation industry standard (MS/NAS) specialty products. It is widely used in aerospace equipment and ground support and maintenance equipment. Each product has a unique code name recognized in the aviation industry. It is commonly used in all major aviation manufacturing industries in the world.

High precision, good finish, no oxide layer on the inner and outer walls of the steel pipe after heat treatment, good cleanness of the inner wall, high pressure bearing, no deformation in cold bending, no crack in flaring and flattening, and various complex deformation and mechanical processing.

The high-pressure stainless steel pipe is made of special stainless steel material. It is seamless and cold-drawn. After work hardening, it has high strength and corrosion resistance. It transmits liquid and gas without leakage. The pressure reaches 60000Pis. It is widely used in high-pressure water jet, high-pressure water cutting and high-pressure cleaning machines. All kinds of liquids and gases can be used.

The invention relates to a method for controlling the precision of a cold finish rolling inner hole and a technology for controlling the smoothness (cleanness) of the inner hole so as to ensure no dust or oil. Steel pipes shall be subject to vacuum bright annealing, degreasing and ultrasonic cleaning. The size is precise, the surface is smooth, the whole is clean, and the single dust-proof package in the dust-free room is dust-free and oil-free.
