![]() The input to our wheel mixers is returnable sand, new sand, bentonite and water. Each bearing gives bentonite the right properties (strength, heat resistance). The bentonite we use is mixed from raw materials from the surroundings of Most and from Slovakia. This is especially important for smooth casting surfaces and to prevent sticking. Mixed bentonite contains carbon, which causes the formation of shiny carbon after casting the mold with metal. The property of bentonite is a high ability to swell when mixed with water, this ability is further increased by natrification. Clay containing more than 80% of montmorillonite (a three-layer mineral). It is a mixture of quartz slag, natrified (activated) mixed bentonite and water. We do not cast in sand, but in a uniform bentonite mixture. Of course, nothing is as simple as it may seem. By fulfilling the standards according to IATF 16949: 2016, we are flexible for changes in the terms and composition of shipped products.įor the general public, Seco Industries, s.r.o. These are just some examples of packaging of castings and cylinder liners in SECO INDUSTRIES, s.r.o., but we can also adapt to individual customer requirements. Wooden crates, in turn, meet customer requirements for the supply of cylinder liners for internal combustion engines. How? For example, environmentally friendly anti-corrosion protection of the surface of castings for overseas deliveries, where we also apply a moisture inhibitor to the packaging unit itself.įor packaging for customers in Europe, we use, among other, multi-layer cardboard boxes with liners and custom-made liners, which prevent movement during transport and damage to castings, while meeting the requirements for automatic handling and unloading on the customer’s line. also offers a comprehensive logistics solution for the supply of castings and cylinder liners not only to the European market, but we also experience in distributions to North and South America and Asia. we also offer machining of castings in our machining shop, which is part of the company’s premises.Įmphasis on operational and fast logistics has never been more justified than in today’s volatile world of trade and services. This makes the casting ready for packaging and subsequent shipment. The castings are blasted and ground a second time to remove any dirt and surface defects. After the castings have cooled, the parts are blasted for the first time from the remnants of sand adhering to their surface and are separated from their inlet system. After casting, the inlet systém castings cool on the conveyors at the end of which the molds are broken on a vibrating grate so that the inlet systems are separated from the sand mold. Inoculation of the the metal stream ensures the correct structure of ductile iron after casting, ie the formation of spheroidal graphite during solidification of the metal, eliminates the effect of inoculum fading and minimizes the necessary amount of inoculum per 1 kg of cast metal. The shape of the ladle guarantees the ideal use of magnesium for modification in the production of ductile iron.Īfter the modification, the slag is removed from the surface and the metal is poured into an automatic casting machine, which casts the metal into molds from a uniform bentonite mixture at a high rate. After melting, correction and inspection of the chemical composition, the metal is poured into a modification ladle. ![]() The charge consisting of a cast iron door, steel scrap, crude iron and alloys is placed in the furnaces by means of vibrating loading trolleys. We have a separate division for the production of cylinder liners. We produce castings for large-scale production of simple and complicated shapes in the weight category of 0.1 to 3 kg. They are designed for compressors and camshafts of internal combustion engines. The foundry produces small castings, used in the automotive field. The technologies of metal melting and subsequent casting are completely independent of each other in both operations, as well as in the entire process of cooling, finishing, final inspection and subsequent dispatch.Ĭurrently, our foundry produces castings for major multinational companies operating worldwide. They are centrifugally cast into shell linings. The gray iron foundry is focused on the production of cylinder liners for diesel engines. Ductile iron castings are cast in sand molds. The foundry of Seco Industries, s.r.o., which is a Czech company, boasts with more than a century of tradition in the production of ductile and gray cast iron castings.
