Encountering a film of dry powder on a new rubber product can be a confusing experience. You may be wondering whether the product is really new or made using an inferior rubber compound. This substance is rubber bloom and while it may not be aesthetically pleasing, it is not unusual to find it even on brand new products.

Let’s delve into the intriguing world of compression set in rubber materials, where resilience and deformation take center stage. Compression set is the most important characteristic of rubber products. And it’s vital to consider this factor when selecting rubber for a specific project. If you don’t pay attention to compression set value, you may pick a material whose application will fail over time. You don’t want that. Do you?

These days, industries have started using eco-friendly products to minimize their carbon footprints. When it comes to high-quality rubber products for medical and other industries, manufacturers prefer silicone over plastic. This rising demand for silicone makes it a significant product to look into. 

Due to the popularity of injection molded products in plastic thermoforming, it is important for manufacturers and designers to be able to identify the right type of surface finish for their specific products.

Low-pressure molding is a crucial innovation with various applications across various industries. This versatile technology offers a cost-effective and efficient solution for sealing, protecting, and encapsulating electronic components, cables, and more. This post will delve into Low-Pressure Molding basics, exploring its significance, applications, and benefits to manufacturers, engineers, and product designers.

Polypropylene fiber plays a vital role in modern concrete construction by addressing challenges such as heavy impact, cracks, structural issues, etc. Including this material in concrete mixes brings countless benefits, such as performance enhancement, sustainable concrete structure, impact resistance, durability, and whatnot. Indeed, the most significant benefit is to control crack formation to maintain structural integrity. 

Do you want to unlock a universe of design possibilities? If yes, you should step into the silicone rubber printing universe, which unwraps a vibrant world of printing innovation. Whether you belong to the fashion industry or craft promotional items, silicone rubber printing techniques allow you to create long-lasting, durable, and high-quality prints. 

How much compression do you need to get a good seal when using a silicone gasket? This is the question that the silicone gasket compression percentage answers. Too little compression will lead to an ineffective seal but too much compression can also result in a gasket that performs poorly even in the short term.

A very common manufacturing process used in industries related to rubber, plastic and other polymers is called molding. There are different types of molding processes that can be used to achieve different goals. The overall aim of the process is to mold the raw materials into any desired shape using a mold cavity.

Injection molding has its fair share in revolutionizing the modern manufacturing industries. This one process has seven different types and each type lets you establish an innovative product industry.  Whether you are interested in modern products or planning to know every bit of injection molding, this comprehensive guide will unravel everything for you.

Navigating the realm of injection molding, one quickly recognizes the paramount importance of an efficient cooling system. This guide delves deep into the intricacies of the cooling process, shedding light on components like cooling channels, and the distinctiveness of air cooling versus water cooling methods.

In injection molding, pressure plays a pivotal role at every stage of the process. From determining the flow of material to influencing surface finish and part complexity, it is imperative to grasp the intricacies of pressure management. With tons of force exerted by the machine per square inch, even slight variations can lead to problems such as defects or inadequate product performance.
