In short, a mold is a thing used to make a shaped object, which is composed of various parts, and different molds are composed of different […]
What are the process requirements for lost foam molds?
The lost foam mold manufacturing process has relatively strict requirements on production conditions, and the quality of castings is more sensitive to the function and stability of raw and auxiliary materials, and various conditions cross-effect, the law is more complicated, and it has not been clarified so far.Just because the process planning is more sensitive […]
Structural requirements of lost foam molding sand box
The key to the success of lost foam mold casting is to understand the importance of close cooperation between casting manufacturers, users and mold designers. The form of the lost foam can be said to be various. In the process of casting the lost foam, of course, it is inseparable from the help of the […]
How to deal with cracks in the mold after the foam mold is quenched
The cracks of the lost foam mold after quenching are a major defect in the heat treatment process of the mold, which will lead to the scrapping of the processed mold and cause great losses in production and economy. (1) CausesThere is severe network carbide segregation in the mold material. There is machining or cold […]
What is the deformation of the lost foam mold casting blank?
One of the casting molds is called lost foam mold casting. One of the common disadvantages is the deformation of the casting blank. During machining, the blank is often scrapped because the size and shape tolerances of the blank do not meet the requirements of the drawings. What is the deformation of the blank? Solution: […]
How to make foam box mold
At present, when foam manufacturers produce foam boxes, they generally use molds to make them. Because the molds need to be continuously repeated, cycle heating, cooling, reheating, and cooling during use, in order to reduce consumption and increase molding speed, The material selected for the mold must be easy to transfer heat, so copper and […]

The utility model discloses a foam mold edge chamfering device, which comprises a fixed block, a power cord and a cutting resistance wire for melting foam. A pair of limit rods are arranged at intervals at one end of the fixed block. There is a connecting rod, the two ends of the cutting resistance wire […]
How to make EPS foam mold
EPS plastic foam is a kind of polystyrene foam plastic. It is widely used in packaging and heat preservation due to its light weight, firmness, shock absorption, low moisture absorption, easy molding, good water resistance, heat insulation, and low price. , waterproof, heat insulation, shock absorption and other fields, is one of the most widely […]
How are foam packaging products made?
Let’s first popularize science on how foam packaging is produced. Foam packaging is made of expandable polystyrene (EPS) raw materials through molds and heat-processed. The packaging products made are commonly known as ‘foam’. Various packages are made by pressing and mold processing, which is foam packaging. Then let’s look at how to manufacture foam packaging […]
