LanguageBy now, you're familiar with concrete's versatility in construction. It's used in essentially any type of construction at some point, so having a better understanding of this material is a good idea if you're preparing for an upcoming project.
An example is understanding concrete mold forms and their importance in ensuring the right look and shape. You should focus more on these forms long before you start your pour.
The Purpose of Concrete Mold Form Products
Concrete mold forms are a particular barrier that facilitates the creation of concrete structures. The concrete molds form is shaped specifically to ensure that the concrete dries correctly and smooth. Newer concrete mold forms might also help make more robust structures, add decorative effects, or provide insulation.
Each type of form has unique properties that make it more suitable for certain projects than others.
Types of Concrete Forms
Concrete forms are divided by what material the form is made of. They're most commonly made from wood, but plastic, metal, resin, and fiberglass are all valid options. However, most prefer wood or metal since these materials work best.
Wood Forms
Wood forms are straightforward. They're easy to construct, and you can often reuse them if they're treated well. Wood mold forms are excellent for smaller structure slabs, sidewalks, and patios.
Gang Form Systems
These systems combine wood and metal like steel or aluminum. These gang mold form systems are more involved in build and use, but their durability and reusability make them great for projects that need many of the same concrete structures.
Manufactured Stone or Concrete Forms
These concrete or stone mold forms are best for larger structures or walls. They can be wood, metal, or a combination of the two. Since these are pre-manufactured, they benefit from professional customization; they arrive at the job to your exact qualifications and can also be reused.
Insulated Concrete Forms
ICFs are made from plastic foam that fit with one another to create the shape you want.
Once you have the right shape, steel bars reinforce the foam before pouring the concrete.
These mold forms are energy efficient and make very durable structures suitable for floors, walls, and roofs. They are not reusable, however.
As cities grow and urban spaces become more densely populated, the need for innovative and efficient urban design solutions becomes increasingly important. Public spaces, streetscapes, and outdoor parks serve as communal gathering points, fostering a sense of community, promoting social interaction, and enhancing the quality of life for residents and visitors alike.
Landscape architects and specifiers working on the design of these shared outdoor spaces may consider utilising precast concrete, given the excellent performance and durability of the material in the outdoor environment. Using modular design as opposed to full custom solutions for outdoor concrete seating can drive certain efficiencies in these streetscape and public applications.
Cost Efficiency
Modular precast seating is an economically efficient choice for urban designers, thanks to the cost savings gained from the reduced initial investment in moulding.
Depending on the complexity of the mould, steel moulds for furniture items can range in price from $5-10,000. However, they can be reused 100+ times, which builds a compelling case for having fewer moulds. With just one or two moulds, hundreds of seating units can be produced, creating large expanses of seating.
Lead Time Savings
SVC's typical lead time on steel mould production for outdoor furniture is approximately six weeks for 1-6 moulds. If more moulds are required, the lead time is extended accordingly. Once the steel moulds are ready for production, precast units can be turned around relatively quickly with each mould capable of producing one unit per day.
Utilising modular design also allows considerable time savings during the design phase of a landscape project – a simpler design consisting of homogeneous repeating modules can be completed with drawings produced in a shorter timeframe than a design involving multiple unique modules.
For designers or developers who are time-poor, SVC also offers a catalogue range of pre-designed precast concrete furniture, some of which are available in modular suites. These designs are made to order with existing moulds ready to be filled, saving time otherwise spent on design and mould production.
Design Flexibility
The concept of modular design may be perceived as having a design outcome that is overly simplistic. This may be true in certain cases if the furniture modules assume simple shapes such as rectangular blocks, corner pieces or curved modules. Simplicity in outdoor furniture is not necessarily a bad thing, as it allows other aspects of the landscape – such as greenery, water features or sculptural elements – to take centre stage.
On the other hand, a high level of design complexity is still achievable with a modular furniture suite, as the individual modules can be customised in terms of colour, aggregate mix or even special design treatments such as stencilling or imprinting of letters or graphics.
Individual modules may also be complex in terms of form, having irregular or asymmetrical shapes. Oddly shaped modules can convey a sense of uniqueness and design complexity, even if the same module is simply rotated or positioned at different angles.
Repeatability
Another benefit of designing streetscapes and public spaces with modular concrete furniture is the ability to repeat the same modular design on a later stage of the project, or even on a different project altogether.
The steel moulds used to create modular concrete furniture can be reused multiple times and are extremely durable, lasting for several years. Reusing an existing modular design also means that project lead times will be significantly reduced, as there is no time required for furniture design or mould production.
Urban designers can use modular furniture suites to develop a unique design style that creates a subtle connection between their landscape projects, giving them ownership of their own unique furniture suite that can be deployed across various applications.
Concrete balusters can add an elegant and regal look to the exterior of your home. Whether you are outfitting an elaborate backyard patio or adding curb appeal to the front of your house, concrete balusters will do the job. If you shop around at specialty stores, you will find that concrete balusters are quite expensive; moreover, they usually require special ordering and professional installation. You can create beautiful concrete balusters for your home without much fuss. To do it, you'll have to allocate the time and pick up a few essential materials.
In order to create concrete balusters yourself, you have to use baluster molds. Usually made of heavy-duty plastic, these molds come with all the hardware you need. You can find these molds at either local home improvement stores, or specialty fixture stores. They may keep a set or two of the mold in stock, but the assortment may be limited. Before deciding on a design, ask to see a catalog of the molds available for order. While the molds are being shipped to you, you can acquire the other necessary materials.
Step 1 - Fit the Mold Together
Once you unpack the mold, you will find that it comes with a set of pins. Sometimes the pins are plastic, and sometimes they are metal. According to the manufacturer's instructions, fit the mold together and secure it with the provided pins. You can coat the inside of the mold with motor oil to assist in releasing the concrete. Don't use unrefined or edible oil. Make sure that the two pieces of the mold are flush with one another so that you don't lose any of the concrete during the process. To make a stronger baluster, cut a ½ inch piece of rebar to size and set it in the middle of the mold. There should be a slot made in the mold so that the rebar remains in the center.
Step 2 - Mix the Concrete
If you are using the recommended white concrete, you should mix 1 part concrete to 2 parts sand. If white concrete is not available, or you simply prefer the Portland cement, mix one part cement with three parts sand.
Step 3 - Add the Concrete to the Mold
Add the mixed concrete to the mold. The most important part about this step is to make sure that while you are adding the concrete, you turn the mold. Keeping the mold moving while you add the concrete ensures a smooth finish.
Step 4 - Remove the Dried Baluster
Once the mold is filled, you have to let it dry. If you are working in the heat of the summer, the drying time could be as short as 12 hours. However, under standard conditions, you should let the concrete baluster dry for at least 24 hours. Once you are sure the cement is dry, lay the mold on its side and remove the pins. Carefully remove the baluster from the mold and place in the desired location.
Repeat the process to make more balusters. Purchasing more than one mold can speed up the process.
There are many positive attributes of the injection molding process, and one of these is the vast array of different industries it can provide products for. Numerous different entities have needs that can be filled by plastic injection molding, and one of the most common in terms of our daily use and interactions is the realm of windows and doors.
Here are some of the chief ways injection molding serves as a valuable process in this industry:
Low installation costs: Because of the way injection molding creates one-piece parts that are very easy to assemble and don't require extra materials like nails, screws, or brackets for support, the overall installation cost is lower than with other methods.
Consistent quality level: In addition, because of how repeatable the injection molding process is, the parts that are created will have a very consistent quality level. This means that you don't have to worry about minor variations in color or strength from one batch to the next, and you can be confident that your product will meet the same standards every time.
Low corrosion risks: Plastic is much less likely to corrode than other materials like metal, so you won't have to worry about the elements affecting your windows and doors.
Improved security: In some cases, injection molded parts can actually improve the security of your windows and doors. For example, if you're using a plastic that's difficult to shatter, it will be much more difficult for would-be burglars to break in.
Low cost: Plastics are cheaper to source than materials like metal, wood and glass, and that's not even the entire picture — they're also lighter, meaning they cost less to transport. Injection molding can create very complex parts at a relatively low cost.
These are just some of the ways that injection molding can be a valuable process for entities in the window and door industry. When you're ready to order your custom injection molded parts, be sure to keep these attributes in mind so you can choose the right materials.
In fact, our next few sections will go over some specific considerations to keep in mind if you're completing a plastic injection mold order within the window and door industry.
First and foremost, you'll need to decide what kind of plastic you want to use. There are a few different options available, each with its own advantages:
ABS: One of the most popular plastics used in injection molding, ABS is known for its strength and durability. It's often used in products that need to withstand heavy wear and tear, and it's also resistant to chemicals and heat.
PC: Polycarbonate is another strong and durable plastic, but it's also transparent, making it a good choice for windows and doors. It's shatter-resistant, so it can improve security, and it's also UV-resistant, meaning it won't fade over time.
Celon (Acetal): This plastic is known for its low friction, making it a good choice for products that will be moving parts (like door hinges). It's also resistant to chemicals and heat, and it has a very low water absorption rate.
Nylon: Nylon is a versatile plastic that can be used in a wide variety of applications. It's strong and durable, but it's also flexible, making it a good choice for products that need to be able to withstand impacts. It's also resistant to abrasion, so it won't wear down over time.
HIPS: HIPS is a good choice for products that need to be stiff and strong, but it's also easy to print and paint. It's often used in applications where aesthetics are important.
Polypropylene: This is a rigid plastic that's known for being lightweight and easy to mold. It's often used in packaging and food service applications because it's safe for contact with food.
In addition, there may be a wide variety of design specifications that you'll need to take into account when choosing your materials. For example, if you're looking for a material that's shatter-resistant, you'll want to make sure it has a high Izod impact rating. If you need a material that's FDA-approved for food contact, on the other hand, you'll need to look for something with a food-grade certification.
There are many other design specifications to consider as well, so be sure to discuss your needs with your plastics supplier. Some window and door companies will care most about things like material recyclability, for instance, while others will be more concerned with things like resistance to UV light or fire. By taking the time to figure out what's most important to your company, you can make sure you choose a material that meets all of your needs.
