Qingdao Zhenganli Metal Manufacturing Co., Ltd.

Though the compare is difficult directly, but ZAL compare with china supplier, we don't compare the price, but provide the higher level quality, rapid response, on time delivery and standard service.

Please send your 2D,3D,PDF or CAD drawings to us, we will provide accurate mold quotation or product quotation .

We are a professional manufacturer more than 20 years, We mainly provide die casting products and molds, also provide maching, CNC,surface.

If you need, we are glad to offer you samples for free, but the new clients are expected to pay the courier cost, and the charge will be deducted from the payment for formal order.

The most commonly used materials in mechanical manufacturing are steel and cast iron, followed by non-ferrous metals. alloy. Non-metallic materials such as plastics, rubber, etc., also have unique use value in mechanical manufacturing. The metal material: 1. Cast iron Both cast iron and steel are iron-carbon alloys, and the difference is mainly due to the difference in carbon content. 2. Steel Steel has high strength, toughness and plasticity, and can be heat treated to improve its mechanical properties and processability. 3. Copper alloy Brass is an alloy of copper and zinc, and contains a small amount of manganese, aluminum, nickel, etc. It has good plasticity and fluidity, so it can be rolled and cast. Non-metallic materials: 1. Rubber The rubber is elastic and absorbs a lot of impact energy. It is often used as a spring element for couplings or shock absorbers. 2. Plastic Plastics have a small specific gravity and are easy to form parts with complex shapes.

Our revolutionary aluminum pressure casting processoffers a number of important benefits including: · Customization:It facilitates the attainment of complex designs and forms, making it easy tocustomize the casting to specific manufacturing processes. · Higherrates: Aluminum alloy die castings enable parts to be manufactured at a muchhigher rate than other metal alloys. Robotic die cast work cells are also usedto increase production efficiency. · Lightweightstrength: Aluminum castings offer the highly valued combination of light weightand superior strength. · Low cost:Aluminum die cast parts are typically less expensive than other metal alloys. · Versatileand resistant to corrosion: Aluminum castings are extremely versatile and offerexcellent resistance against corrosion.

Before replacing the parts, some maintenance personnel do not perform technical inspections on the new parts and directly install them on the construction machinery. This is unscientific. At present, the quality of spare parts sold on the market is uneven, and some counterfeit and shoddy parts are mixed with beads; some accessories have changed performance due to excessive inventory time. If they are not tested, they often cause failure after assembly. Be sure to carry out the necessary inspections and tests before replacing the new parts. The tests include appearance and performance tests to ensure that the new parts are not faulty and prevent unnecessary troubles.

When the machine fails, it must be tested by the testing equipment. If there is no testing equipment, it can be determined by the traditional fault judgment methods and means such as “question, see, check, test”, combined with the structure and working principle of the construction machinery. The most likely area of failure. When judging the failure of construction machinery, the "exclusion method" and "comparative method" are generally used, and the order is from simple to complex, and the internal and the first assembly are re-assembled in the order of the first and the first assembly, and it is forbidden to "disregard the indiscriminate, blindly dismantling and unloading."
