The use of the excavator is extensive, and it can be seen in any construction area. The mini excavator has attracted more attention because of its mini body. Its smart and convenient operation brings efficiency and quality to the project. Today, let us take a look at the advantages of small excavators.
Bobcat Mini Excavator
1, because its size is not large, so the price is also cheaper, full-featured, very light in operation, has been welcomed by more people, although small but not unambiguous in the construction, and in some special places Large excavators are not available during construction.
2. It can also remove the front end bucket and install the broken hammer for road construction. The small advantage is reflected. The light weight has no more load on the ground and is also efficient in the operation process.
3, the model is different, for more consumers to choose, small excavators suitable for their own project work will bring a lot of construction assistance. (This article is from the Bobcats)
Lost Wax Casting is the main technology of investment castings. In most conditions, it can be regarded as Investment Casting. The main process of lost wax castings is: mould design--mould making--wax injection--tree assembly--shell making-dewax-shell roasting-pouring-cleaning-heat treatment-machining-package.
Advantages of lost wax castings:
a, Accuracy: dimension tolerance--CT5~CT7,roughness--Ra2.5~6.3μm,weights range from 10g to 80kg;
b,Surface shape and inner cavity is almost not limited, we could manufacture lost wax castings with minimum wall thickness 0.5mm;
c, Almost all kinds of material can be used, such as steel, aluminum, copper, superalloy and so on.
Disadvantage of lost wax castings:
The production cycle is relatively long and it is not suitable for large products in terms of the features of this kind of process.
Classification of lost wax casting:
1. Sodium silicate casting: large surface roughness, low dimension accuracy with short shell making cycle. The hardening technique is chemical process. Normally most of Carbon Steel Investment Casting and alloy Steel investment casting are made by this kind of lost wax casting process.
2. Silica sol casting: Small roughness, high dimension accuracy with high material costs and long shell making time. The hardening process of shell is a natural process under certain temperature and humidity. Normally stainless steel investment castings are made by this kind of lost wax casting process.
As a leading manufacturer of lost wax castings, A&M has the experience to produce almost all types of lost wax castings. Most of our lost wax castings are widely used in automotive, aerospace, marine, medical equipment, power plants and other industries
