Fourstar Rubber is a unique and privately owned and operated Michigan Company specializing in rubber molding. Founded in 1988, the company has built a reputation of being resourceful, knowledgeable and reliable. With over 45 years of rubber and mold manufacturing experience, the principals remain actively involved in the design and manufacturing activities.
Molding is a manufacturing process that uses a mold - the latter being a solid container used to give shape to a piece of material. It is a forming process. The form is transferred from the mold to the material by...
Grommet edging protects electrical cables, wires and other sensitive components from abrasion and chafing as they pass through or over rough or sharp edges or surfaces. Chafing can lead not only to loss of data and operational...
Rubber injection molding is when uncured rubber is transformed into a usable product by injecting raw rubber material into a mold cavity made of metal. The applied pressure produces a chemical reaction like...
Rubber latches are latches made of rubber or are composed of rubber components. They are used in the automotive, aerospace, and medical equipment industries due to their flexibility, durability, and non-abrasive properties...
Rubber molding is a process of transforming uncured rubber or an elastomer into a usable product by transferring, compressing, or injecting raw rubber material into a metal mold cavity...
There are several methods to perform rubber overmolding, and each method has its own unique advantages and disadvantages. The choice of method typically depends on the design and material requirements of the product being...
Silicone rubber molding is a method for shaping, forming, and fabricating silicone rubber parts and products using a heated mold. The process involves compressing or injecting silicone rubber into a mold where it takes the shape and form of the mold cavity...
A rubber bushing is a form of vibration isolator that is placed between two parts to limit the motion between them and absorb, mollify, and buffer the energy produced by their interaction. They are very...
Extruded rubber is a group of products made by softening and pressurizing an elastomeric compound and forcing it to flow through a hard tool called a die. The resulting product is a continuous piece of material that has the same cross-section throughout its length...
Rubber gaskets are elastic components used for mechanically sealing the microscopic gap between two mating surfaces or joints. Examples of these surfaces are flange faces of piping and fittings, mating surfaces of an...
Rubber to metal bonding is when a rubber part has to be adhered to a metal part, a metal component is chemically prepared and is attached or encapsulated as part of the process to become a bonded rubber part...
Urethane casting is the process of injecting polyurethane and additive resins into a soft mold usually made of silicone elastomer. The casting process is similar to injection molding; injection molding differs by using hard, metal molds...
