What are the main defects of Motorcycle engine cover die casting?
Answer: There are undercasting (not full of material), cracks, deformation, cold separation, cold lines, shrinkage, pores (sand holes), mechanical strain, sticky mold strain, delamination, wrong mold, slag inclusion, surface cavitation , Blistering, fleshy, lack of meat, etc.

What is the temperature of the aluminum alloy liquid suitable for die-casting production?
Answer: 650℃~720℃

What are the characteristics of die casting production?
Answer: (1) High production efficiency, mechanized or automated production can be realized;
(2) Good product quality: A, high dimensional accuracy, high surface finish; B, good mechanical properties; C, good interchangeability; D, clear outline, thin and complex castings, patterns, patterns, characters, etc. can be obtained High definition
(3) Good economic effect: A. Excellent economic indicators; B. Low cost of die castings; C. Can be used as a combination of parts;
(4) Die-casting equipment and molds have high investment costs and are not suitable for small batch production.

What aspects are involved in the design of die castings?
1. That is, the requirements of pressure casting on the shape and structure of parts;
2. Process performance of die castings;
3. The dimensional accuracy and surface requirements of die castings;
d. Determination of parting surface of die-casting parts; part design of die-casting parts is an important part of die-casting production technology. The following issues must be considered when designing: selection of mold parting surface, gate opening, selection of ejector position, casting The shrinkage of the casting, the guarantee of the dimensional accuracy of the casting, the prevention of the internal defects of the casting, the relevant requirements of the casting hole, the relevant requirements of the shrinkage and the size of the machining allowance, etc.;

What are the design principles of die castings?
a. Correctly select the material of die castings,
b. Reasonably determine the dimensional accuracy of die castings;
c. Try to make the wall thickness evenly distributed;
d. Add craft round corners at each corner to avoid sharp corners.

Come vengono fabbricati i prodotti di fonderia per l’automotive?I componenti automobilistici vengono realizzati utilizzando diverse tecniche. I principali processi impiegati nella produzione devono garantire risultati efficienti e leggeri. Per raggiungere tali obiettivi, vengono adottati i seguenti procedimenti.
Pressofusione ad alta pressioneQuesto processo consente di ottenere prodotti con una minore porosità e una maggiore perfezione. La pressofusione ad alta pressione è il metodo più diffuso nella produzione di componenti pressofusi per l’automotive. Essa sfrutta tecniche di pressione per riempire lo stampo con metallo fuso e per estrarre dallo stampo il pezzo finito. Le tecniche di pressione permettono di realizzare componenti complessi e riducono la necessità di ulteriori parti da assemblare.
