We need make wooden, resin or metal patterns according to the drawings or samples. Then, we put patterns into the sand boxes, then put green sand or resin sand into the boxes, then make the sand become solid by pressure come from molding machines or manual methods, then take the patterns out, and so, the space taken by patterns will become hollow, then inject melted liquid iron into the hollow space, then after cooling, the hot iron water will become iron parts, the after sand blasting process, remove the sand on the surfaces, and we will get the clean cast iron parts.

The prices of sand castings depends on rough casting cost, machining cost, surface coating cost, heat treatment, packing and delivery costs. You could find the FOB China prices on the main page of Dandong Foundry in China.

Normally, metal foundries do not make wooden and resin patterns in-house. However, some large foundries with machining capability could make the metal patterns by themselves. But as for the complex metal patterns, only the professional pattern workshops could meet the requirements.

As for wooden and resin patterns, the workshops need some manual tools and simple lathes. As for metal patterns, the workshops needs some CNC centers, numerical control milling machines, wire-electrode cuttings.

3.2.1. Manual molding, it is very traditional molding method, which is also called as hand molding. Workers use simple tools and sand boxes to complete the molding process. This method still has very wide application. Almost all metal foundries are still using this method to deal with small batch production or special sizes of castings.

3.2.2. Molding machines. These machines include mechanical molding machines or simple Leak mould machine. Leak mould machines do not have wide application since their low production rate and dimensional restriction. Molding machines are still widely used, they have their advantages, however, because of their comparatively low production rate, they have been replaced by automatic molding line step by step. 3.2.3. Automatic molding lines. These molding lines have very high production rate, so more and more iron foundries are importing them, and they are perfect for producing automotive parts.

3.3.1. Sand blasting equipments are the main cleaning equipments, and there are mainly hook-type, crawler, transfer desktop shot blasting machines. After sand blasting, the castings will need workers to grind them by grinding tools to remove the burrs and sharp edges.

The melting furnaces main include medium frequency induction furnace and traditional cupola. More and more metal foundries have imported induction furnaces to replace cupola in order to improve the production rate and casting quality.

3.4.1. Most of metal foundries in China have their own machining equipments in-house. At least, they could complete the simple or rough machining by themselves. Some larger foundries have high precision machining tools.

Sand castings could be widely used for many industrial and residential fields, mainly include stove and boiler parts, agricultural and engineering machinery parts, pump and valve bodies, pipe fittings, drainage parts etc.

Metal foundries normally completes the visual inspection, dimensional inspection, physical properties (hardness, tensile strength) and chemical component. As for some special tests, such as the sharp impact test, pressure test, x-ray inspection, magnaflux inspection and ultrasonic test, some professional suppliers could complete them in-house, but most of suppliers will have to entrust professional labs.

In China, there are some different metal castings suppliers. Some are professional machining workshops, but they have their foundry partners. Some are professional metal foundries. Some are just trading companies, which have their own sub-suppliers.

Kolene Recover is a mid-temperature (300F - 325F) organic fluid paint stripping process. Compatible with a wide variety of metals, Recover can strip E-coat and powder coating quickly and without any base metal attack. Even highly polished components such as aluminum wheels can be safely stripped with no dulling. For more information about the Recover Process, visit Paint & Powder Stripping Reject & Salvage Stripping.

The de facto standard for ultimate casting cleanliness, our Kastech Electrolytic process can safely remove scale, sand, and even graphite from the surfaces of cast iron components. Internal passages are as easily cleaned as exterior surfaces. Also specified as Kolene No. 4 Electrolytic, it is ideal for hydraulic and pneumatic components. Components that will be brazed or babbitted also benefit from Kastech Electrolytic processing with superior bond strengths.

Kastech AL750 is ideal for leaching residual silica investment from aluminum castings. After knock-out and mechanical cleaning, AL750 can easily digest the silica from internal passages or blind areas where mechanical methods cannot reach. For more information, visit Casting Cleaning Aluminum Investment.

Kolene offers cleaning services for ferrous and select non-ferrous investment castings. After mechanical pre-cleaning, molten salt leeching provides rapid and thorough removal of residual shell and coring. Our processes are effective on most silica containing shell and core compositionsand are equally effective for cleaning castings and risers, gating, etc. in preparation for alloy reclamation.For more information, visit Casting Cleaning Investment.

Iron metal is not only an important basic strategic material, but also one of the main raw materials for steel production. Pure magnetite can be directly put into the furnace to make iron, but generally speaking, there are not many high-grade magnetite. The processing of iron ore mainly goes through the processes of crushing, grinding, beneficiation, and drying, among which the crushing process is the primary and important link in iron ore processing.

The first stage: crushing & screening three stage closed-circuit crushingLarge pieces of iron ore are uniformly sent to the jaw crusher or coarse crushing mobile station by the vibrating feeder for coarse crushing; the coarsely crushed iron ore is screened by the vibrating screen and sent to the single-cylinder hydraulic cone crusher for processing Medium crushing: The iron ore material after medium crushing is sent to a multi-cylinder hydraulic cone crusher for fine crushing.

The second stage: grindingThe iron powder of 0-12 mm sieved by the vibrating screen is evenly sent to the mill for grinding, and then sieved by the spiral classifier, and the iron powder that does not meet the requirements is sent to the mill to continue grinding.
