TTWB, TTWP, and TTOP: Mold Temperature Controller Series Selection

2026/04/11 By le zhan

Mold Temperature Controller-3-3

Topstar’s TTWB, TTWP, and TTOP mold temperature controller series are engineered to meet the specific process requirements of specialized industries. The TTWP series is available in a “Pure Water” version and a “High Flow” version, while the TTOP series is the “Oil-based” version. Unlike standard models, these mold temperature controllers are typically used in applications such as 3D printing, optics, medical manufacturing, and large-scale injection molding. To assist users in selecting the most suitable controller for their specific production types and requirements, we have provided a comparative overview of these models, helping you understand their practical applications in real-world production environments when making your purchasing decision.

Comparison of the TTWP and TTOP Mold Temperature Controller Series

TTOP Oil-type VersionOil-type Mold Temperature Controller320°C high-temperature stability, leak-proof designAluminum die casting molds and continuous high-load production

TTWP Pure Water Version: Ideal for Pure Water Circuits and Contamination-Sensitive Environments

The TTWP Pure Water version is specifically designed for applications that require the circulating medium to maintain an exceptionally high level of purity. It features an independently isolated water tank, ensuring that the water circulating through the mold remains a high-purity medium. This design keeps the internal circuit completely separate from the external cooling water circuit, eliminating the risk of cross-contamination right at the source. Furthermore, this water-type mold temperature controller incorporates a 316L stainless steel heater to prevent contamination of the circulating water. This design ensures that the heating system itself remains clean and stable, rather than introducing potential risks to the production process. This model works especially well for industries like 3D printing, optics, medical device manufacturing, and precision mold fabrication fields that usually need very stable temperature control and ultra-clean circulation systems because their products are highly sensitive to contamination.

TTWP High Flow Version: Ideal for Large Injection-Molded Parts

Engineers design the TTWP High Flow version for large-scale injection molding scenarios that demand exceptionally high cooling efficiency and fast cycle times. It utilizes a multi-stage centrifugal pump and an enlarged piping design to achieve high flow rates. This configuration accelerates and stabilizes heat transfer between the mold and the controller, thereby reducing the overall molding cycle. Additionally, this model uses large-diameter solenoid valves, which help speed up cooling and make temperature control more precise. The TTWP series is the preferred choice for manufacturing components such as automotive bumpers, refrigerator casings, air conditioner housings, washing machine panels, waste bins, and other large-format parts components that require a mold temperature controller capable of effectively managing greater thermal inertia and meeting higher cooling demands. Furthermore, it delivers enhanced cooling capabilities for the process without compromising control quality.

The TTOP Oil-Type: Engineered for the High-Load, Continuous Production Environments of the Die Casting Industry

The TTOP oil-type comprises oil-type mold temperature controllers specifically designed for die-casting applications, making them particularly suitable for aluminum die-casting molds. The operating temperature conditions for these molds are far more demanding than those for standard injection molds; consequently, the controller must deliver a stable high-temperature output and respond rapidly to process fluctuations.

It supports oil-type mold temperature control up to 320°C, providing the stable high-temperature output required for die casting. Featuring a leak-proof design, engineers built the unit to withstand the typical high-load, continuous-production conditions found in the die-casting industry. Additionally, it employs a magnetic-drive pump to minimize the risk of high-temperature fluid leakage, thereby enhancing safety and ensuring more environmentally friendly operation. We have also implemented a split-design architecture for the electrical cabinet and heating system to prevent heat transfer that could damage internal components, thereby enhancing operational stability. The TTOP series uses shut-off valves that can withstand temperatures up to 320°C. This feature further contributes to both safety and durability.

The Core and Intelligent Control Capabilities of the Mold Temperature Controller

Topstar’s entire range of mold temperature controllers uses a third-generation PID control algorithm, enabling them to adaptively respond to fluctuations in both mold and ambient temperatures and achieve ±0.5 °C precision. This control system, featuring adaptive logic, helps maintain a stable output even when process conditions are not entirely constant. We also employ SSR drivers, which boast a response time of just 0.1 seconds, ensuring more precise temperature control and extending the equipment’s service life. For production teams, using Topstar mold temperature controllers results in reduced temperature fluctuations, fewer process adjustments, and more consistent part quality.

Intelligent Mold Temperature Control

In the context of intelligent manufacturing management, mold temperature controllers must be easy to monitor and readily connectable to a factory’s digital systems. The entire Topstar series features a 7-inch touchscreen interface, enabling operators to clearly view temperature data, operational status, and alarm notifications. This design enables operators to grasp the system’s status at a glance without navigating complex menu structures.

These mold temperature controllers also support programmable scheduling, allowing users to set automatic start-up and shut-down times up to one week in advance. Leveraging such programmable scheduling helps improve energy efficiency and facilitates better factory planning. All mold temperature controllers include an RS485 communication interface that supports the MODBUS protocol. This enables seamless integration with factory automation systems, facilitating remote monitoring and data acquisition. In a smart manufacturing environment, networked mold temperature controllers empower management personnel to gain comprehensive insights into the production process.

How should I choose?

If your workshop requires a water-based mold temperature controller, the TTWP series is an excellent choice. If your application demands an oil-based mold temperature controller to accommodate higher operating temperatures, the TTOP series is more suitable. When the circulating medium needs to stay highly pure and you must strictly avoid cross-contamination, choose the TTWP Pure Water version. For larger molds with high thermal loads where faster cooling speeds are required to shorten cycle times, select the TTWP High-Flow version. Finally, for die-casting applications requiring oil-based stability at temperatures up to 320°C, as well as prolonged, continuous, and high-load operation, the TTOP series is the ideal solution.
