Klatrefasen: Det første trin er at forberede formhalvdelene til støbning ved at rengøre fladerne på hver form og derefter påføre smøring eller slipmiddel. Når formen er klargjort, lukkes formhalvdelene og spændes sammen med et tryk fra trykstøbemaskinen. Spændekraften afhænger af maskinens størrelse, men skal være større end den modsatte kraft, der forsøger at åbne matricen under støbeprocessen. Indsprøjtningsfasen: Barrerne lægges i ovnen og holdes smeltet ved en bestemt temperatur alt efter, hvilket metal der skal bruges. Det smeltede metal overføres til et indsprøjtningskammer og sprøjtes ind i den lukkede form med et tryk på mellem 1000 og 20.000 psi. Trykket opretholdes, mens metallet størkner. Mængden, der sprøjtes ind i matricen, kaldes ‘skuddet’ Indsprøjtningen af metal i matricen er meget kort, hvilket sikrer, at metallerne ikke begynder at størkne, før matricen er helt fyldt. Afkølingsfasen: Når indsprøjtningen er færdig, skal det smeltede metal størkne, før matricen åbnes. Afkølingstiden afhænger af emnets geometri og metallets termodynamiske egenskaber. Emnets vægtykkelse spiller en stor rolle for afkølingstiden; jo tykkere vægsektionen er, desto længere afkølingstid kræves der. Udstødningsfasen: Når køletiden er gået, kan de to matricehalvdele åbnes. En udstødningsmekanisme skubber derefter den størknede støbning ud af formen. Udstødningskraften bestemmes af emnets størrelse, og man skal huske på, at emnet krymper under afkølingsprocessen og har tendens til at klæbe til formens overflade. Når emnet er skubbet ud, kan matricen lukkes, så den er klar til næste indsprøjtningscyklus. Trimmingsfasen Under afkølings- og størkningsfasen størkner støbningen som en komplet støbt enhed, der omfatter emnet, flash og et eventuelt løbesystem. Dette overskydende materiale skal trimmes af, så der kun er det støbte hovedprodukt tilbage. Metoden til trimning omfatter trimmeværktøjer, båndsav og manuel klipning. Alt afkortet metal bliver enten skrottet eller genanvendt, hvis det er tilladt. Fordele ved trykstøbning: Trykstøbning er hurtig Trykstøbning kan produceres på få sekunder for hver del og i mængder på hundreder til tusinder af metaldele hver dag. Nær nettoform Trykstøbning produceres “nær nettoform”, uanset hvor kompleks formen er, og hvor snævre tolerancerne er. Lettere vægt Trykstøbning er stærkere på grund af materialets overflade og ikke materialets tykkelse, så dele kan veje mindre med tyndere støbevægstykkelser. Trykstøbning er alsidig Mange flere emneformer og -størrelser kan produceres ved hjælp af trykstøbningsprocessen. Trykstøbning er holdbart Trykstøbte dele er af metal og har en lang levetid. Trykstøbninger er billige Trykstøbninger er hurtige at producere og ubrugelige materialer. Trykstøbning er typisk billigere end de fleste andre fremstillingsprocesser for metaldele.

The process of die casting with pressure injection can be followed until mid-1800. The components used were tin and lead, but the use has disappeared with the introduction of zinc and Aluminium alloys. This process has evolved over the years, from low-pressure injection molds to casting molds at pressures of up to 4,500 psi. The process can create high-quality products with excellent end surfaces. Die Casting is an economical and efficient process for making various shapes. Considered superior to other manufacturing techniques, it is durable and aesthetic and combines perfectly with other parts of the machine that are part thereof. Dying has many advantages. Among these, the main is its ability to produce complex forms with a higher tolerance level than other mass-production methods. Thousands of identical prints can be produced before you need to add new mold tools. High Die-pressure is a manufacturing process where aluminum that has been melted is injected by a casting machine under extreme pressure on steel or molds to make the design and detail parts of the model you want to make. Casting in tons of universal tightening. This record reflects the amount of pressure given on the matrix. The engine size varies from 400 to 4000 tons. There are many advantages to using the die casting process compared to others. Die casting produces parts with thinner walls, narrower size limits and processes can be accelerated. Labor costs and finishing are the lowest with the dice. This process facilitates to obtain intricate forms with narrower tolerances. Unlike the forgery process, you can insert the kernel into the product created by this process. Forms that cannot be obtained from rods or tubes can be easily achieved with casting. The number of operational processes is smaller, which leads to the reduction of waste materials. Die casting is used when you need a stable, dimensional and durable component. They withstand heat and maintain a good level of tolerance, an important condition for each part of a good machine. They are stronger and lighter than the part made by other printing methods. Its parts are not welded or screwed, which greatly increases its efficiency. Another advantage is the many workarounds that you can get with the launch. Surfaces can be smooth or textured, which facilitates the application and its use. Hopefully, this information can help you and thank you for reading the article about Zinc Die casting.

Zinc die casting Parts is referred to as the hot-chamber process. It is the method by which zinc (zamak) is heated under high temperatures and the molten material forced into a zinc die casting mold under high pressure to produce product with a similar shape as the die. As the metal moves through the die, air escapes through the vents. Once the die is full, the high pressure is maintained until it solidifies and the die is separated to release the finished zinc cast. After casting, no further modification is usually required. Use of Zinc Die Casting Zinc (zamak) is known for its high strength, accuracy, ductility, ease of casting, high thermal and electrical conductivity, and long life. As such, the zinc die casting is applied in the manufacture of high quality industrial and building materials. Die casting started in the automotive industry and it is still widely used in the manufacture of automotive components. The door locks casing, pulley, and the camshaft are some of the car parts that are made of zinc casting. In the construction industry, zinc die casting is utilized in the manufacture of components such as door knobs, faucets, and roofing. On the other hand, there are many zinc casting machine parts, such as electrical fittings. Zinc Die Casting Process Zinc is cast using the hot-chamber process due to its low melting temperatures. Cold chamber process is applied in the casting of metals with high melting temperatures such as the aluminium. The zinc die casting process involves the preparation of the metal, die preparation, and finishing. It commences with the preparation of the die followed by the metal. Notably, the die can be used once or severally depending on the component being manufactured. If it was used before, it should be lubricated to ease the removal of the cast metal. Afterwards, the ejector die half and the cover die half are screwed. The cover die half has a sprue through which the molten metal is injected while the ejector die has ejector pins for removing the castings. Preparation of the die is followed by melting of the ZA or the ZAMALAK alloy on a furnace. The physical properties of the product dictates the choice of the alloy. Due to metal hardness and strength, the furnace temperature is usually very high. The oxidized parts of the metal are removed at this stage to raise the purity of the finished product. Various chemicals can be added to improve physical properties of the finished alloy. Once the molten metal is prepared, it is injected into the feed system under high pressure. Most of the systems have several dies for efficiency and mass production. The raised pressure ensures that the molten zinc alloy gets into the mold as fast as possible, no air gets into the molten metal, and the expulsion of the air in the die through the vents. After filling the die, the pressure is raised further until the zinc alloy casting solidifies. The process also involves cooling using water. Then, the two dies are separated and the metal cast is removed. This is followed by the cleaning of the feed system to get rid of the flash. Further finishing can be carried out depending with the final use of the product. The runner that is removed from the final product and the flash are usually recycled.

In 2011, the competition in the hex bolt China engineering machinery market will be more intensely, on the basis of enhancing domestic enterprises’ self-confidence previously, the battle of Chinese engineering machinery market is bound to become fiercely, except the competition between domestic jaw crusher brands, the competition with foreign brands also will continue to upgrade with the pace of China local enterprises’ international development accelerating. China blow molding machine market has attracted international attention with its rapid development in 2010. Under the guidance of the state a series of correct measures, the bag making machine industry economic operation maintains steady and rapid growth; the main economic benefit indices are better. 2011 is the beginning year of the Twelfth Five Year, under the pressure of the state strengthening the macroeconomic regulation and the real estate industry’s control, the growth rate of engineering plastic valve industry will fall back significantly. Under the inflation pressure, the terminal sales of blow molding machine industry will be influenced to a certain degree. But these are not able to stop the engineering machinery market to go strong clip continuously, the signing of the indemnification house construction sign military order and the new investment upsurge of water conservancy construction have shored up Chinese engineering machinery market to a great extent. The major medium-sized PVC fitting enterprises have begun to expand their production capacity and market share in 2010, which has left hidden unsafety for the overcapacity of engineering slitting machine market in 2011 or even the future. The capacity expansion has promoted the demand for engineering machinery market tending to saturation; however, the increasing white hot of engineering machinery market has speeded up the pace of capacity expansion. If this situation is not improved, the continuous cycle certainly will result in overcapacity. As for the current development situation of Chinese engineering machinery market, the products such as excavators, cranes and concrete machinery have huge development potential, and the market is optimistic. Take the excavator industry as an example, enterprises such as Wuliangye, Rongan, Chery and Geely have turned around the excavator market. Such a large scale cross-industry restructuring, combined with the uneven brand degree, product performance and quality of engineering machinery market, it not only will impact the whole industry sales, but also will trigger a series of low-end overcapacity, and even lead to unfair competition in the industry. In addition, at the beginning of this year, from the recruitment situation all over the country, we can see that the talent shortage is particularly acute in construction machinery industry, especially the urgent need for high-end integrated talent, not a “labour shortage ” can be described. The labour costs rising and the raw material costs increase is certainly a challenge for engineering machines industry. Especially at present, many enterprises are facing that no matter how high wages they provide, they still can’t recruit much-needed talent. In 2011, the competition in engineering machinery market will be even more intense, under the situation of all kinds of risks, China construction machinery industry must have a long-term perspective, while occupying mainland market actively, it also should accelerate the pace of approaching overseas market, speed up energy saving pace, and find new opportunities for the transformation development of machinery enterprise constantly in crisis.
