Soft tooling is a process that uses silicone or other soft materials to produce molds for low volume runs. In this process, the mold is produced by pouring silicone into a master model of the part. The silicone mold is then used to produce the part using conventional injection molding techniques. One of the advantages of this process is that it can produce parts with complex geometries in a relatively short amount of time, and at a lower cost than conventional injection molding. However, the mold material is not as durable as steel or aluminum, so the number of parts that can be produced is limited.

Mold Design: Design the mold with precision to accommodate the desired part geometry, gating, venting, and cooling requirements for PEEK injection molding. Consider features such as draft angles, parting lines, and vent channels to facilitate mold release and minimize defects.

Traditionally, because of high tooling costs, injection molding is usually regarded as a manufacturing process for high-volume and mass-scale production.

The injection molding process is swift and intense, utilizing high heat and pressure to inject molten material into a carefully crafted mold. The choice of molten material depends on the scope of the manufacturing project, with popular options like ABS, PS, PE, PC, PP, or TPU, though even metals and ceramics can undergo injection molding. The mold itself comprises a cavity designed to closely mirror the final features of the desired part.

Mold Temperature Control: Maintain precise control over mold temperature using water or oil circulation systems to achieve uniform cooling and solidification of the PEEK material, preventing defects such as warpage, shrinkage, or surface irregularities.

While 3D printing molds offer significant advantages when used appropriately, certain limitations should be considered. Expectations should not equate 3D printed polymer molds with machined metallic ones in terms of performance. Critical dimensions may be harder to meet, and longer cooling times may be required due to slower thermal transfer in plastic. Additionally, 3D printed molds can be more susceptible to breaking under heat and pressure.

Another big reason to invest in tailored solutions from our injection molding company is that these hold excellent suitability in varied applications.
