Plastic prototyping is a common practice for plastic manufacturers. It is important to understand what it is and why it matters. What is plastic prototyping? Plastic prototyping is a crucial stage in product development where a plastics manufacturer creates a preliminary version of a product using plastic materials. This process allows for testing and validating design concepts before moving on to mass production. By utilizing various plastic molding techniques, such as injection molding or 3D printing, manufacturers can quickly and cost-effectively produce prototypes that closely resemble the ..read more

When you need plastic parts for your product, you want a plastics manufacturer that is reliable, affordable and produces good-quality parts. There may be a lot of options, so it is important to narrow down the field with the right criteria. What is a plastics manufacturer, and what do they do? A plastics manufacturer is a company that produces plastic parts. The most common way this is done is through injection molding, but some plastics are made with methods such as blow molding or extrusion. A plastics manufacturer may also build molds, prototype parts, or offer post-production services such ..read more

Injection molding parameters are not something you would be expected to know about unless you worked in injection molding. But when preparing a machine, an injection molding parameters sheet must be closely followed to avoid bad parts or damage to machines.  What are injection molding parameters? Parameters are guidelines or rules, so for an injection molding machine, parameters are the specific settings for multiple aspects of their operation to run for a certain part. These parameters must be followed for the plastic material to flow smoothly through the machine and into the mold and to ..read more

When making injection molded plastic parts, there are many things that can go wrong. It’s vital to tune injection molding machines and molds for parts to the right specification to prevent such errors. At Rex Plastics, we understand the importance in producing the highest rate of quality parts that we can. Minimizing rejected parts saves time and money—both for us and our customers. Flash is one of these defects, and we have years of experience in understanding how to reduce flash in injection molding. In the image to the right, you can see flash around the edges of the shape.

What is a plastic hinge? In injection molding, a plastic hinge refers to a specialized feature designed within a plastic part to provide flexibility and allow rotational movement. The plastic hinge design allows it to endure repeated cycles of bending or flexing without causing permanent deformation or failure of the part. Using the inherent elasticity and flexibility of certain plastic materials, such as polypropylene or polyethylene, plastic hinges allow for rotation within a part without inserting another material. This functional and cost-effective mechanism within injection-molded product ..read more

Custom plastic injection molding is a manufacturing process that involves the creation of a three-dimensional object by injecting molten plastic into a mold. This technique produces plastic parts with high precision and consistency, making it a popular choice in various industries such as automotive, medical, and consumer goods. With custom plastic molding, companies can create unique products that meet their specific requirements and design needs. The process begins with the design of a mold, which is then filled with melted plastic under high pressure. Once the plastic cools and solidifies ..read more

What is a plastic injection molding machine? Plastic injection molding machines are used to manufacture large quantities of plastic parts. People use them in various industries, including automotive, aerospace, medical, and consumer products. Injection molded parts are made by melting plastic pellets and injecting them into a mold cavity. The desired part shape is formed, the part is cooled, and is ejected from the mold. There are many different types of plastic injection molding machines available, each with unique features and capabilities. Some machines are better for high-volume production ..read more

What are threaded inserts? Threaded inserts are small, often cylindrical, parts that you can insert into a hole in a plastic part during the molding process to provide a threaded hole for a screw or bolt. Threaded insert design typically uses metal, such as steel, brass, or aluminum inserts, and comes in various thread types and sizes. You can install them into a plastic part using multiple methods, including ultrasonic welding, heat staking, and press-fitting. What are threaded inserts used for? People use threaded inserts to provide a strong and durable thread in plastic parts, whi ..read more
