When you’re choosing a manufacturing process for plastic parts, two common options often come up: compression molding and thermoforming. At first glance, they may look similar—both use heat and pressure to shape materials—but the way they form parts, the type of products they suit, and the level of detail they can achieve are quite different. […]
Compression Moulding vs Thermoforming: Key Differences Read More »
In rubber and thermoset manufacturing, transfer molding and compression molding stand out as two of the most widely applied methods. Both are effective for producing durable, heat-resistant, and dimensionally stable rubber products, yet they differ significantly in operation, cost, and design flexibility. What Is Compression Molding? Compression molding applies heat and pressure to shape materials.

Compression molding is often perceived as a simpler alternative to injection molding, with fewer design constraints. This leads to a common misunderstanding that part design is less critical in the process. In reality, compression molding follows a different design logic. Instead of controlling melt flow under high pressure like injection molding, it relies on material

Silicone overmolding involves bonding silicone materials to a substrate to create integrated parts. The primary material used in this process is liquid silicone rubber (LSR), which offers excellent flow properties for precise injection. However, other forms exist, including high-temperature vulcanizing (HTV) silicone for applications requiring higher hardness or lower costs, and room-temperature vulcanizing (RTV) silicone

The water assisted injection molding process, one of injection molding types, builds on traditional injection molding by using water pressure to displace material and form internal cavities. It addresses challenges in thick-walled components. The water assisted injection molding technique is widely used for lightweight , hollow, and structurally stable plastic components. What is Water Assisted

Before a plastic part ever reaches mass production, it usually has to go through one critical step: prototyping. A CAD model may look perfect on screen, but once it is translated into a physical part, issues related to fit, strength, assembly, or manufacturability often start to appear. A good prototype helps identify design issues early,

In injection molding, corners are one of the most sensitive features in a plastic part design. Sharp edges can lead to stress concentration, poor flow during filling, and higher risk of cracking or warping. In contrast, well-designed radiused corners help the material flow more smoothly into the cavity, improve structural strength, and reduce mold wear

Medical silicone molding is an important technology for both implantable and non-implantable medical components. Implantable parts, such as seals in pacemakers or catheter tips, remain inside the body for extended periods and require long-term stability. Non-implantable parts, including surgical instrument handles or respiratory masks, contact the body temporarily and focus on ease of sterilization. This
