There are many foundries in China and even in the world, and there are also many foundries with high quality and good performance. Buyers often seek the most optimal configuration, namely: the lowest cost and good quality. Generally speaking, find a relatively large processing factory in the surrounding area, visit it, and ask if there is any outsourcing processing order. Participate in some industry exhibitions, or offline procurement and supply matchmaking meetings, meet procurement and match orders face to face. These methods can find a reliable foundry

What factors affect a reliable foundry: procurement distance, casting quality, and casting price.

1. The distance between the foundry and the purchaser's factory
Logistics costs account for a certain proportion of purchase costs, and the farther the distance is, the higher the purchase price will be. The farther the distance, the higher the cost of transportation time, the more external factors are affected, and the longer the delivery cycle. The editor of the foundry believes that under the same conditions, the closer the foundry is, the higher the reliability is.

2. The quality of castings. Only when the quality of castings meets the technical requirements can the foundry be reliable.
Product quality is the foundation of enterprise development, without product quality is equivalent to a tree without roots. It mainly includes appearance quality, internal quality and use quality. Appearance quality refers to the surface roughness, surface defects, size deviation, shape deviation, and weight deviation of castings; internal quality mainly refers to the chemical composition, physical properties, mechanical properties, metallographic structure of castings and the holes, cracks, inclusions, Segregation, etc.; use quality refers to the working durability of castings under different conditions, including wear resistance, corrosion resistance, shock resistance to cold and heat, fatigue, shock absorption, etc., as well as process properties such as machinability and weldability.

The quality of castings has a great influence on the performance of mechanical products. For example, the wear resistance and dimensional stability of machine tool castings directly affect the precision and maintenance life of the machine tool; the size, accuracy and surface roughness of the impeller, housing and hydraulic parts of various pumps directly affect the pump The working efficiency of the hydraulic system, the development of energy consumption and cavitation, etc.; the strength and shock resistance of the internal combustion engine cylinder block, cylinder head, cylinder liner, piston ring, exhaust pipe and other castings directly affect the working life of the engine.

A foundry without quality, let alone reliable.

3. Casting price
In the daily customer inquiry process, some customers will complain that there are many foundries that can cast and process, but the price is relatively expensive. It can be seen that the price of castings plays an important role in the procurement process. We often hope that Buy high quality and low price products.

Materials commonly used in foundry production include various metals, coke, wood, plastics, gas and liquid fuels, molding materials, etc. The required equipment includes various metal smelting furnaces, various sand mixers, various molding machines, and molding cores Machines, etc., sand blasting machines and shot blasting machines for cleaning castings. There are also machines and equipment for special castings, as well as a lot of transport and material handling equipment.

Casting production has the characteristics of wide adaptability, many materials and equipment, and large environmental pollution. The dust, harmful gas and noise produced in the casting production process pollute the environment more seriously than other mechanical manufacturing processes, and measures need to be taken to control it.

Henan Greenland Tech focuses on precision casting and large castings, using silica sol casting, sand casting, and lost foam casting processes. We wish everyone to find a reliable foundry!
