Product Introduction

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

±0.05mm Platen Accuracy High-Response Dual Proportional Valves 99%+ Force Uniformity Three-Rod Single-Cylinder Braking

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 high clamping force makes it ideal for producing large, heavy-duty components such as automotive chassis parts, industrial machinery housings, and other demanding large-format applications that require consistent, high-pressure mold clamping.
Q What platen movement accuracy does the SK-2400U guarantee?
The SK-2400U guarantees a platen movement accuracy of ±0.05mm, achieved through its high-rigidity clamping unit paired with advanced L-shaped rail precision guidance systems on a solid machine frame. This level of accuracy is critical for producing large components with extremely tight tolerances and ensuring every finished part meets the most exacting industry standards.
Q How does the SK-2400U protect molds during operation?
The SK-2400U features the SK-U series intelligent slow-down control system, which achieves the strict A4 paper rebound protection level. This ultra-sensitive mold protection system halts the machine immediately upon detecting even minimal interference during mold closing, fully protecting expensive molds from damage and maximizing their operational lifespan.
Q What are the available screw diameter options for the SK-2400U?
The SK-2400U is available in three injection unit configurations — A, B, and C — with screw diameters of 160mm, 170mm, and 180mm respectively. Each configuration offers different shot sizes, injection weights, injection rates, and plasticizing capacities, allowing manufacturers to select the most suitable setup for their specific material and production requirements.
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 mold opening and easy tie-bar extraction. This makes the machine perfectly adaptable to low-headroom facilities and simplifies installation in factories with height restrictions, while also supporting the complexities of modern multi-variety production environments.
Q What makes the SK-2400U more durable than conventional injection molding machines?
The SK-2400U's durability is engineered through uniform-stress guide posts that undergo special surface treatment for superior wear and corrosion resistance. These guide posts achieve over 99% force uniformity, which prevents eccentric loading during high-pressure clamping cycles. Combined with the reinforced platen design and the three-rod single-cylinder synchronous braking system, the machine maintains structural integrity and high performance even under continuous, heavy-duty production conditions.
