Hot runner solutions
As a result of continuous product development and considerable investment, Thermoplay is considered a global leader in hot runner system solutions.  A team of researchers and specialized technicians, aware of customer requirements in a continuously evolving market, enables the development of a flexible and easy-to-manage range of products. Prototypes are tested using a wide range of plastic materials and undergo simulations to verify performance during the transformation process.

Our continuous technological research enhances the quality and performance of our products and has facilitated the patenting of several innovative functioning principles. Due to the strategic partnerships we develop with our customers during the design process, we can provide a high level of technical advice to achieve the best solution for any type of injection requirement, thus optimizing the process and tool costs.

The product range, designed and built exclusively in-house, consists of a vast selection of standard and special hot runner systems, including complete hot halves, temperature controllers, simulation analysis, simultaneous injection of different colors and materials, and state-of-the-art custom projects.

Thermoplay distributes the majority of its products throughout Europe and offers excellent service in the packaging market, which includes caps and closures, personal care, and medical. Additional key markets for Thermoplay are automotive, electronics, and white goods.

Flow analisys
Injection systems from Thermoplay are defined following careful analysis of the injection material, the size and weight of the item to be moulded, and the expected moulding cycle.
Using flow-analysis software and 3D simulation techniques, the company balances the hot runner carefully to ensure perfect cavity filling for precise production of part details.
Conical plugs inserted in all the manifolds eliminate the possibility of stagnation zones.

The flow paths having the same length and channel sections create a natural balance, while the distributed filling pressure in all the mould chambers ensures moulding of identical parts.

The special structure of the manifold allows the nozzles to be assembled at low temperatures, to avoid out-of-axis movements while the operating temperature is reached.

Special solutions

Thanks to many years of improved experience in hot runner systems design and manufacturing, Thermoplay is able to provide a complete range of standard and special injection systems, suitable for any kind of application including multiple material components and application to large moulds:

• DL1B-DL8B - special edge gate nozzles.
• DL90 - multi-tip edge gate nozzle.
• DN5 - multi-tip nozzle.
• Complete assembled hot half system.
• Special hot half system for injection blow moulding.

Success in the hot running moulding depends on the perfect cooperation with customer in the design process, with simple rules application in process control

Webcreator online

WEBCREATOR is a web-based design application for configuring Thermoplay Hot Runner Systems with standard nozzles and accessories. This generates high quality CAD 2D and 3D models reducing the production time.

The hot runner system is freely configured in relation to the distance between the nozzles and accounts for the polymer processing conditions. The diameter of the manifold channels, as well as of the descent holes to the nozzles and the injection bushing size are configured to suit.

After configuration the 2D drawings and 3D models are generated in the selected format and sent by email to the user in a single zipped file, which also includes the configuration sheet and part list (in pdf format).

Any configurations made can be modified to generate a new drawing later. WEBCREATOR does not perform any check on the configured system in relation to the injected polymer.
