Product Introduction

SK-2400U 2400Ton Two-Platen Injection Molding Machine: The Versatile Industrial Powerhouse for Heavy-Duty Large-Component Molding

Engineered for heavy-duty industrial manufacturing, the SUCCESSOR SK-2400U Two-Platen Injection Molding Machine stands out with its upgraded power, enhanced structural rigidity, and superior adaptability for the most challenging manufacturing applications, embodying the SK-U series' core commitment to engineering excellence. This model is custom-designed for manufacturers that need a robust and versatile machine capable of handling the most demanding large-format applications, from automotive chassis components to industrial machinery housings, with uncompromising molding speed and finished part quality. Its outstanding performance is anchored by a high-rigidity clamping unit, precisely paired with advanced precision guidance systems, which ensures stable platen movement with a guaranteed accuracy of ±0.05mm. This level of precision is absolutely critical for producing large components with the tightest tolerances, ensuring every part meets the most exacting industry standards.

To maximize production efficiency and finished product yield, the SK-2400U is equipped with a three-rod, single-cylinder braking system. This configuration ensures precise synchronization during all mold operations, eliminating timing errors that can lead to part defects and significantly boosting overall product yield, protecting your production profitability. The machine's performance is further amplified by an instantaneous response system, integrated with high-response dual proportional valves. This combination delivers rapid, reliable action response, reducing overall cycle times and improving overall productivity, even on the most complex and demanding molding applications. Flexibility is built into every aspect of its design; the independent high-pressure cylinder allows for controlled slow high-pressure opening and easy tie-bar extraction, making it perfectly adaptable to low-headroom facilities and the complexities of modern multi-variety production environments.

Durability is a key engineering focus of the SK-2400U, achieved through uniform-stress guide posts that are specially treated for superior wear and corrosion resistance. These guide posts achieve over 99% force uniformity, preventing eccentric loading during high-pressure clamping and maximizing the machine's long service life even in harsh production environments. The reinforced platen enhances overall mold stability during production, while the extended stroke accommodates deep-cavity molds, providing a more cost-effective solution than investing in higher-spec three-plate machines. The streamlined design simplifies daily maintenance, and the automated setup system enables quick and efficient mold changes, minimizing downtime and maximizing production uptime. The SK-2400U is a versatile and reliable solution, perfectly suited for high-demand industrial production that requires a powerful, precise, and durable machine to meet the most stringent production goals.

Frequently Asked Questions
Q
What is the clamping force of the SK-2400U Two-Platen Injection Molding Machine?
The SK-2400U delivers a clamping force of 24,000 KN (2,400 tons). This substantial clamping power makes it ideal for producing large-format industrial components such as automotive chassis parts, industrial machinery housings, and other heavy-duty applications that demand consistent, high-pressure mold closure.
Q
What platen movement precision does the SK-2400U guarantee?
The SK-2400U features a high-rigidity clamping unit paired with advanced L-shaped rail precision guidance systems, guaranteeing stable platen movement accuracy of ±0.05mm. This level of precision is critical for producing large components with the tightest dimensional tolerances and ensures consistent part quality across every production run.
Q
How does the SK-2400U protect molds during operation?
The SK-2400U incorporates the SK-U series intelligent slow-down control system, which achieves the strict A4 paper rebound protection level — one of the most sensitive mold protection standards in the industry. The machine halts immediately upon detecting minimal interference, fully safeguarding expensive molds from damage and reducing costly downtime caused by mold repairs.
Q
What are the maximum and minimum mold heights supported by the SK-2400U?
The SK-2400U supports a maximum mold height of 1,900 mm and a minimum mold height of 800 mm, with a maximum daylight of 3,700 mm and an opening stroke of 2,900/1,800 mm. This wide range of mold accommodation makes it highly versatile, capable of handling both deep-cavity molds and standard production tooling without requiring additional equipment investment.
Q
Is the SK-2400U suitable for low-headroom factory environments?
Yes. The SK-2400U is specifically designed with an independent high-pressure cylinder that enables controlled slow high-pressure opening and easy tie-bar extraction.
