Longhua injection chamber (shot sleeve) serves as the core part of the die casting shot system. Fabricated from premium hot work die steel with nitriding treatment, it delivers excellent hardness and wear resistance. Compatible with plunger tips for aluminum die casting, we offer custom sizes for various requirements.
Material Parameters
Made of high-performance hot work die steel. The base material reaches a heat treatment hardness of HRC45-48. Nitriding layer depth: 0.25-0.3 mm, nitrided surface hardness ≥HV900.
Product Advantages
Easy to assemble and disassemble, wear-resistant and high-temperature resistant with excellent cooling performance, impact resistance and corrosion resistance. Customization is available according to customer drawings. The average service life of a single unit is ≥30,000 shots, durable with competitive price and reliable quality.
Application
Special sleeve for the injection system of die casting machines. Matched with the injection plunger, it delivers molten aluminum from the sleeve to the mold cavity to complete the injection forming process.

FAQ
Q1: Who is Longhua?
Bengbu Longhua Die Casting Machine Co., Ltd is a national high-tech enterprise specializing in the R&D and manufacturing of high-speed and high-precision AI die casting machines and intelligent equipment. Integrating design, R&D, manufacturing and sales, we serve the non-ferrous metal deep processing market in more than 45 countries and regions worldwide.
Q2: What are your main products?
Our main products include cold chamber die casting machines, hot chamber die casting machines, die casting molds, die casting robots, industrial automation and peripheral equipment.
Q3: What is your shot sleeve made of?
Our shot sleeve adopts premium hot work die steel, processed with precision machining and deep nitriding treatment to achieve outstanding wear resistance and high-temperature performance.
Q4: What is the function of nitriding treatment on shot sleeve?
Nitriding treatment forms a high-hardness protective layer on the inner wall surface of the shot sleeve. It greatly improves high-temperature wear resistance, reduces aluminum adhesion and thermal fatigue cracking, effectively extending the service life during continuous die casting cycles.
Q5: Can you customize shot sleeves according to our drawings?
Yes. We support custom production of shot sleeves of different sizes to match various die casting machine models.
Q6: What is the lead time for custom shot sleeves?
The lead time depends on product specifications and order quantity. Please send us your drawing and requirement for an accurate delivery schedule.
