In the world of plastic manufacturing, two major categories dominate the molding process: thermoplastic materials and thermosetting materials. Though they may look similar in the final product, the wa...
In the mold and tooling industry, choosing the right steel is crucial for product quality, cost control, and production efficiency. In this article, I want to explore some common questions I had while...
![[Case Study] Shipping Plastic Parts with Embedded Magnets: The Unexpected Challenge We Faced with Magnetism Test Requirements](/uploads/opro-engineering/20250603/3891dded-67f0-41da-b59e-e6c1979829fe.png)
We recently shipped a batch of 350 plastic components, each ultrasonically welded with a small but strong neodymium magnet inside, to a client overseas who urgently needed the parts for a product laun...
In modern manufacturing and product assembly, Formed-In-Place Gasket (FIPG) technology has become a widely adopted sealing method across industries such as automotive, electronics, and industrial equi...
In the tooling and mold manufacturing industry, precision and safety are everything. Even small oversights can lead to costly mistakes — or even permanent damage to the mold. Today, we want to share a...
In tooling and injection molding, creating a bushing with internal threads is a common yet challenging task. The complexity increases when dealing with low-volume production runs, where the cost of ad...
In the field of injection molding and tooling, several advanced technologies have emerged to meet the growing demand for aesthetic design, functionality, and product integration. Among them, IMD, IML,...
Ultrasonic welding is a widely used and highly efficient method for joining plastic components—particularly in automotive, electronics, and consumer products industries. But to truly take advantage of...
As someone in sales, I always strive to learn more about the technical aspects of the manufacturing process. One key area I’ve been diving into is how plastic material data sheets influence mold desig...
In injection molding, one of the most common challenges manufacturers face is the demolding problem, where the molded part sticks to the cavity or core side of the mold, making it difficult to eject t...
Silicone rubber keypads are widely used in various electronic devices, including remote controls, industrial equipment, automotive systems, and medical instruments. While at first glance, they may see...
Shrinkage refers to the reduction in size (volume or dimensions) of a plastic part as it cools and solidifies in the mold. It happens because plastics contract when they change from a molten (liquid)...
