Silicones are the polymers that consist mostly of silicon (sometimes mistakenly spelled cilicone), oxygen, hydrogen and carbon. These polymers are used in production of silicone rubber, silicone resign, silicone grease and silicone oil. Silicones possess several extremely useful properties that give them clear advantage over the other materials used for the same purposes.

Silicone rubber keypads are:

• Chemically inert
  • Nontoxic
  • Thermally stable, meaning that their physical properties do not change over a large range of temperatures (-100°C to 250 °C)
  • Resistant to microbiological growth
  • Waterproof (this quality allows the use of silicones as watertight seals)
  • Non-sticky, which comes in handy when silicon rubber buttons are used in the electronic products that require manual operations (oscilloscopes, ammeters, programmable logic controllers, etc)
  • Electrical insulators
  • Resistant to ultraviolet light (UV light), ozone and oxygen
  • Non-corrosive
  • Eco-friendly

Silicones as chemical compounds

Silicones rubber is a mixture of organic and inorganic components whose general chemical formula is [R2SiO], where R stands for either methyl or ethyl or phenyl organic groups of molecules, depending on the application. (Si-O-Si-O-Si-O …) are the chains of inorganic silicone-oxygen molecules.

Silicone rubber’s properties depend on spatial positions of the Si-O chains and the chain lengths. It is possible to change physical properties of a silicone rubber compound by changing positions of its molecules.

Advantages of using silicone rubber buttons in electronic products

Electronic products such as remote controls, industrial keypads, medical devices, calculators and many other small electronics have incorporated the use of silicone rubber buttons. Silicone rubber buttons are resilient to many external forces, provide tactile feedback, and can be printed on and numerous other features. One of the most common features of silicone rubber keypads is molding a carbon contact pill on the backside. The carbon contact pill will complete a circuit on a PCB when the silicone rubber is pressed. This method of completing a circuit is cost effective and very reliable because it removes the need for a mechanical tactile switch.

When electronic devices are operated at low temperature, the buttons must still function properly when pressed. These buttons are often made out of silicone rubber because of its ability to withstand very low temperatures.
Ultraviolet light is used in many medical devices. Silicone rubber buttons are an ideal choice of relays for these devices because of silicone’s ability to resist the UV light.

Being non-toxic, silicone rubber buttons do not release harmful toxins into the atmosphere. Electronic toys for children are equipped with such buttons so that the children are not exposed to harmful toxins.

One of the main advantages of silicone rubber buttons is their low price. It makes sense for the companies producing electronic equipment to use these buttons to help keep their production prices low.

Its properties include:

1.High temperature resistance

Silicone can operate in temperatures up to 500 degrees Fahrenheit and can withstand extremely cold temperatures.

2. Flame retardancy

Silicone is nonflammable and self-extinguishing, making it a safe material for many applications.

3. Chemical resistance

Silicone is resistant to many chemicals and oils, making it a great choice for chemical processing and automotive applications.

4. Water resistance

Silicone is hydrophobic and resistant to water, making it a great choice for outdoor applications.

5. Electrical insulation

Silicone is an excellent insulator and does not attract dust or dirt, making it ideal for electrical components.

6. Non-toxicity

Silicone is non-toxic and does not emit any harmful fumes or odors, making it safe.

Reinforcing Agents: including glass fiber (GF), carbon fiber (CF), nanoparticles, etc., which can improve the strength, stiffness, and heat resistance of PP.

Flame Retardants: such as aluminum hydroxide, magnesium hydroxide, etc., which can improve the flame retardant performance of PP.

Fillers: such as talc, calcium oxide, calcium silicate, etc., which can reduce the cost of PP and improve its physical properties.

Functional additives: such as antioxidants, UV absorbers, light stabilizers, lubricants, etc., which can improve the service life and stability of PP.

Elastomer toughening agents: such as EPDM, SBS, SEBS, etc., which can improve the toughness and impact strength of PP.

Weathering agents: such as silane coupling agents, organic titanium, etc., which can improve the weather resistance and anti-aging performance of PP.

Reflective agents: such as micro glass beads, metal films, etc., which can improve the reflective performance of PP, and are widely used in traffic safety facilities, protective equipment, and other fields.

Different PP modified materials should be selected according to specific usage scenarios and requirements.

Two Types of Tending: Manually and Automatically Trimmed Gates
There are two types of gates that are used in plastic injection molding: manually trimmed and automatically trimmed gates. With manually trimmed gates, an operator must separate the parts from the runners after every cycle. Manually trimmed gates are used when the material used for the part must not be exposed to the forces of automatic shearing or when the gate is too thick to be separated automatically.
With automatically trimmed gates, no human intervention is needed to separate parts from runners. When the tool opens to eject the part, it is automatically sheared from the runner. Robots and other automation equipment used with automatic trimming can also reduce scratching and labor content.  This also eliminates the need for manual separating as an additional operation and ensures that cycle times remain constant.

Common Plastic Gate Designs
While gates come in a wide range of designs, four of the most commonly used are:
Edge Gate. Probably the most common gate design, it is best suited for flat parts and is located (not surprisingly) on the edge of the part. Edge gates work well with medium and thick sections, and can be used on multicavity two-plate tools. They leave a scar at the parting line.

Sub Gate. This design is the only automatically trimmed gate on the list, and it requires ejector pins. A very common gate, it has a number of variations, some with memorable names like the smiley gate and the banana gate, as well as the tunnel gate. Sub gates can be used away from the parting line, giving you great flexibility in placement. They leave a very small scar on parts.
Direct or Sprue Gate. This manually trimmed gate is used to produce symmetrical filling of single cavity molds for large cylindrical parts. Easy to design and with low maintenance costs, it produces parts that are typically lower stressed and high strength. This gate leaves a significant scar at the point of contact.

Hot Tip Gate. Typically located at the top of a part as opposed to the parting line, this type of gate is great for conical or round shapes that require uniform flow. This type of gate requires a heated element to deliver hot material directly to the part, but it can improve flow and reduce cycle times. It leaves a small raised spot on the surface of the part.

Gate design is a critical component of the injection molding design process. Accessing the variables like part/mold design, material selection, and production intentions are important considerations when deciding what gate design is right for the job. In our more than two decades in plastic injection molding, we’ve seen gate designs that produced outstanding parts and others that required a trip back to the drawing board. As a result, we have significant expertise in this area and can provide tremendous insight on your mold design. We hope this serves as a core understanding or gating and what options are available.

Close up of a standard molded plastic part. Standard Injection Molding: This basic technique uses a single color and material to produce the plastic part. It is commonly used to manufacture everything from beverage containers, caps, electronics, medical devices components, Lighting parts to auto parts and toys, etc…

Overmolding: This is a two-step process used to produce items that require two different types of plastic — for example, a shaped handle with a soft outer material that makes it easier to grip.

First, the substrate plastic part is produced; then each part is individually moved to another mold where another thermoplastic part is molded over the substrate plastic part. The bond between the two materials can be mechanical or chemical.

Insert molding: Insert molding is an application in which a prefabricated part is used as the substrate. This substrate may be made of an alternative material to plastic (often it’s metal).

Knobs and dials that have a plastic exterior over a metal interior are examples of insert molding. The substrate is inserted into the mold, then plastic is injected onto it. Typically this process uses thermoplastic resin as the overmolding material.

A two-shot molding assembly setup, also called double-color injection molding. Two-shot (dual-shot) molding: This is also a two-step injection molding technique, but it is done in one molding press and it allows you to create a plastic part or product using multiple colors and plastic types simultaneously, without having to use a multi-stage assembly process. For instance, you might want to create a plastic power tool housing with a branded-color handle.

First, a substrate is injected by the primary press barrel. Then, mold steel is exchanged and a second injection unit molds the second shot. The bond between the materials can be chemical or mechanical.
