What is post mold cure oven?

Post mold curing involves exposing a section of the mold to an elevated temperature to speed up the overall curing process and maximize the material’s physical property.

A Post Mold Cure Oven is made up of a fully automated system comprising a single cold chamber and ten hot chambers.

The system can automatically process products both in-line and in stacked magazine arrangements.

The PC control system makes it possible to control and monitor the individual temperature-controlled chamber.

Our Post Mold Cure Oven includes a very accurate handling system featuring a reliable temperature control mechanism.


Control system

  • Supports PC control interface/ inspection
  • LCD Screen
  • Hot and Cold Chamber individual temperature control unit
  • Easy to use Un-loader

Handling System

  • The Chamber doors are designed to open and close automatically.
  • Reliable pre-loading /off-loading protection features
  • Supports Stack magazines loader
  • Features three axes hence auto-pick and place


  • Over-temperature protection mechanism

Advantages and unique features

The system comprises ten individual temperature control chambers and one cold temperature control chamber. A fully automated handling system that comprises automated chamber door opening and closing.

Each chamber is manufactured using high quality and polished stainless steel featuring a double skin construction to guarantee high heating efficiency. Low thermal mass insulating material tightly sealed between the outer and inner chamber.

To ensure air circulation is maintained, the system comes with a fan guided air circulation in an enclosed fan ventilation motor.

Adjustable chamber ventilation for effectively exhausting any unwanted fumes. The system has a very user-friendly interface, thus making it easy to learn and operate with a few simple training tips.

It features a modular design, Accuracy, and Repeatability and is Quick and Easy to maintain, thus reducing your machine downtime significantly.

Generally, more cost-effective solutions and reduced Cost of Ownership are ideal for high volume manufacturing due to the improved product quality, Productivity improvement and generally reduced cost.

Heat curing vs post-curing

Heat Curing is used to accelerate the curing process of plastics, epoxy resins, polyurethane rubbers and platinum silicone rubbers and other materials.

For example, when you subject a urethane rubber mold to moderate heat, say(150°F / 60°C), the curing time is reduced by approximately 12 hours ( from 16 hours to about 4 hours)

Post Curing. Generally, when it comes to mold making, post-curing mold rubber helps enhance the physical and performance properties of the molded rubber.

Procedure: After a normal curing cycle for a typical mold rubber (about 16 to 24 hours), the resulting cured mold is exposed to moderate heat (150°F / 65°C) for 4 to 8 hours.

For example, Platinum Silicone Rubber is post-cured at relatively higher temperatures to improve the heat resistance of the mold. This results in a prolonged mold life ideal for casting metals or pewter.

How to cure silicone mold

Typically, it takes approximately 24 hours for silicone sealants to cure completely. After this point, you can expose your silicone mold to moisture, water and other weather elements without causing any damage.

Heat curing (Platinum-cure Silicone) involves elevating temperature since it helps reduce the pot life and curing time of platinum activated silicone rubber.

Indeed, most mold makers apply heat to accelerate the curing time, i.e. de-molding the platinum activated silicone molds. Remember curing your silicone molds helps increase their heat resistance.

Indeed, if you want higher heat resistance with your silicone molds, then make sure to cure for at least two hours with a temperature range of 150°F (65°C), the two endless hours at 212°F (100°C).

Allow the mold to cool to room temperature before you think of de-molding. Best heat sources. An industrial post-mould oven is highly recommended when curing your silicone mold.

This is because it helps in applying a constant and uniform heating area. For best results and your safety, never use a kitchen mold.

Post mold cure oven uses and applications

As the name suggests, post-mould curing is done once the material has been cured for at least 11to13 hours. A complete cure is achieved at room temperature within 7 to 10 days for thermoset material.

Post-cure ovens are used to accelerate the curing effect to speed up this process. Once a complete cure is achieved, you can now expose the material to water and moisture.

Remember, Post curing helps expedite the even-linking process and cross aligning the entire polymer molecules.

Post curing thermosets can help improve the physical properties such as tensile strength, heat distortion temperature and flexure strength higher than what average temperature can achieve.
