Which Type of Moulding Process Is Suitable for Your Application?

When determining the most suitable type of moulding process to use, you need to take several factors into consideration. Some of the factors include:

• The volume of parts needed
• The material needed
• The weight of your part
• The geometry and size of your part

 

Rubber Compression Moulding

The original method of moulding rubber is compression moulding. It is suitable for low to medium production volume and a very useful process for moulding O-rings, seals, gaskets, and large, bulky parts. It is an efficient, commonly used, and economic method for producing many parts, especially low production volumes of medium to large parts as well as higher cost materials. It is only possible for compression moulding to be cost-effective if the following is true:

• Larger parts are required
• Extreme hardness or strong rubber bonding of materials is needed
• It can be applied to bond rubber to metal
• Only a low quantity is required

 

Rubber Transfer Moulding

Transfer combines the ease of compression moulding with the advantage of injection moulding. Rubber transfer moulding is a suitable process for moulding intricate parts that require a closed mould, parts that require multiple cavities, bonding rubber to metal parts and if the part’s geometry can cause the cavities in the mould to trap air. Why Transfer Moulding is Better Than Compression Moulding:

• Simpler and fewer pre-forms since a single pre-form can fil multiple cavities.
• Tighter control over dimensional tolerance since the mould is closed, which means that excess material spilling out of the cavity parting line during moulding does not hold it open. This ensures that the geometry of the part is kept exact and the parting lines are less noticeable and smaller.

 

Injection Moulding

Rubber injection moulding was initially an offshoot from the plastics industry back in the early ‘60s, once the initial issues temperatures, (plastics are cooled during moulding while rubber is heated), and pressure (rubber injection requires significantly higher amounts of pressure per square inch of the cavity surface) were overcome. Rubber injection moulding is of 3 main types:
 

1. Organic Rubber Injection

The first step in organic rubber injection is the efficient preparation of materials. The material is mixed and stripped into continuous strips then fed into a screw that charges a barrel as required with a pre-determined quantity of material. Once the mould is closed, the material within the barrel is injected into mould cavities then cured. Benefits of Injection Moulding:

• Total elimination of operator placement of pre-forms
• Moderately faster cycle times than transfer and compression moulding
• The material is pre-heated by the injection screw before it is forced into the cavities thus reducing the viscosity of the material and letting it flow easily into the cavities

 

2. Injection or Liquid Injection Moulding (LIM)

It is a process where 2-part liquid silicone compounds are delivered at a constant ratio into a mixer that’s static. The LSR mixture then blends with a platinum cure system then delivered to the injection unit where it is injected via a gate and runner system into the closed mould until it is cured. Once the cycle is complete, the parts are ejected or removed from the cavities and the next cycle starts. Benefits of Liquid Injection Moulding:

• Optimized cycle times
• Parts are almost “flash-less”
• Contamination is limited by automatic closed-loop systems
• It is perfectly suited to the unique needs of the medical product industry
• High-quality components that have complex shapes can be repeated cost-effectively in large quantities

 

3. Thermoplastic Rubber Injection

It is a process that utilises thermoplastic elastomers (TPE) with properties and performance similar to rubber but is processed like plastic. Benefits of using TPE as opposed to thermoset rubber:

• Recyclable parts and scrap
• TPEs can be coloured
• Parts cost less because of thinner and lower density wall sections
• Simplified processing since no vulcanization or mixing is involved.

What to Know Before Wearing Hair Weave

What is a new hair style that you really wish to try? If you ask me, my dream is to have a long curly layered hair with bang that similar with the looks of some famous persons whom I saw in online magazines.

How to Keep the Peace on Divided Social Media Networks

During elections, viral social topics, and shocking cases that make national news, friends and family may engage in heated debates on multiple social media networks. As emotions and tempers run rampant, it can seem as if it is impossible to prevent these heated discussions or arguments, especially on one's personal account. The comments or messages left behind could be rather embarrassing or hurtful. With a few modifications, social media can be a far friendlier place to visit.

Openly Supporting Equality

Equality is a prominent social issue in many countries across the world. As people of different colors, races, and orientations fight for their rights, many people still fight against equality. By supporting particular causes, such as promoting racial equality, one can instill a sense of love and acceptance within their social media circles. Being a loving and supporting individual reduces the risk of outcries or backlash on social media networks.

 

Muting, Deleting, or Blocking Connections

For certain friends or family members, their opinions could be rather harsh and outspoken; some are downright cruel. Some people might even try to incite hate or arguments, which may warrant deleting or blocking that individual from the account. Others, who simply have unpopular opinions and are outspoken, can simply be muted. Many social networks allow members to hide certain posts from their followers. This keeps those followers from seeing or commenting on posts that they would feel the need to discuss.

 

Setting Rules for Social Interaction

If things seem to get out of hand often, the account holder can message the offending followers, friends, or family members and request that they refrain from sharing particular opinions on the member's posts. Many people will respect those wishes in the future. For the people who don't, it might be worth removing them from the account or simply muting them on posts and shares.

 

Steering Clear of Controversy

Some posts might encourage negative reactions from family or friends, and are quite controversial. Political, parenting, social rights, and religious posts can fall into this category. Instead of sharing posts like these, an individual could simply share updates regarding his or her family, inspirational quotes, interesting projects, and much more. Funny summaries of the day's events with the children and cute pictures of pets are always a wonderful way to sweeten up social network accounts. Social media is a wonderful place to connect with friends and family. When things get hairy, many people can be left feeling hurt or betrayed. Instead, keep negative feedback at bay to maintain a happy and loving connection with friends and family.

Features to Consider When Seeking the Perfect Location for Your Short Film

Creating a film of any type requires careful selection of the location where you will shoot the scenes. Finding the best location should therefore be at the core of preparing to film the movie. The location is important as it helps to support the story you want to tell. It also offers an attractive backdrop for your short film, therefore making it more interesting.

Your choice of location requires careful consideration. The process of making the final decision of the location is dependent on a number of factors. You need to check the features of the location with respect to the factors that affect the outcome of the movie as a whole. It is possible to find perfect locations.

You can start with familiar locations that are within your reach if you are on a budget. You can also find locations that are open to movie producers such as yourself. You can find online sites such as photoshootlocations.com that help to link property owners with the film industry. You can easily type in the search parameters of your ideal location and get a list of possible properties.

When choosing a location, consider the following:

The characters

The location you pick should help in building the characters you have in the short film. If your character is a cook, for example, you may want to shoot his or her scenes in a kitchen perhaps. A rich and powerful character will need a mansion or an opulent office to show off these characteristics. The location should help in bringing together the story that you want to tell. It is therefore important you find a location that allows you to do this.

The scene

The scene should go together with the location you film it in. For example, a romantic evening should have the best location to portray this. It could be a scene you want to shoot at the park with the couple strolling, or it can be a restaurant or dining room that brings the idea of a romantic dinner. The location you choose should therefore match the scene that you will shoot at for it to support the story you are trying to tell.

Lighting and other factors that affect filming

The location should make your filming process easier. If it will be hard for the filming crew to shoot the movie, then you need to reconsider. Consider issues such as lighting, camera angles and the like. If you really need to use the location, then you may have to see if you need to bring in additional equipment such as additional lighting or cranes for the cameraman.

If you are on a tight budget, you may have to reconsider and either change locations or find a way around the difficulties. You can opt to use a different camera size perhaps, change positions of the scene or shoot at a certain time of the day when the lighting is just perfect. The perfect location may also be problematic and you just have to find a solution in order to end up with a perfect film.
