.Bowling balls have really come a long way, from the round stones that may have been thrown at pin like stones by the caveman, and most assuredly be the ancient Egyptians, to the “resin particle cover stocks” with unimaginable weight block shapes that are driving up averages today.
The Dutch introduced a game similar to what we play today to America during the colonial period, possibly. This game evolved into the game of “nine pin” which became a very popular gambling game, the authorities of the time eventually banned the sport of “nine Pin”. In order to skirt the ban on “nine Pin” it is popularly believed that a tenth pin was added to the deck, thus the game we know as “ten pin bowling”. The ball used for these games and up to the very early 20th century was made of a very dense hardwood, lignum vitae. In 1905 the first rubber ball, named the “Evertrue” was introduced, about this time the 16-pound maximum weight limit was imposed. Then in 1914 the “Mineralite” ball was introduced by the Brunswick Corporation, then a maker of billiards balls, and was successfully promoted, touting its “mysterious rubber compound”. These types of bowling ball, and variations of it, were the mainstays until about the 1970’s.
During the early 1970’s polyester/plastic bowling balls were introduced. The characteristics of these bowling balls are low production costs, which allows lower costs for bowlers buying their own equipment, durability, many color or design choices. The disadvantages are that these balls do not “grip” the lane very well and usually go very straight, however the tendency to go straight does make them very popular as a spare ball, and many are used today just for that purpose. Most bowling center have a selection of house balls for the patrons to use, most of those balls are either hard rubber or polyester bowling ball.
In 1981 Ebonite developed the technology to produce a polyurethane cover stock, however this was a higher cost process, and Ebonite, fearing that the bowler would not pay the estimated $80 sale price, sold the manufacturing rights the AMF. The result was the production of the “Angle”, and the modern era of bowling balls was born. This new cover stock allowed more friction or “grip on the lane, resulting in a ball that was more controllable, predictable, smoother roll, and was easy to hook or curve into the strike pocket. The cover stock was also “adjustable” as to how aggressive the hook or curve was, by varying how it was finished, need less hook, polish the ball, need more hook, sand the surface. The “urethane balls are durable, last a long time, require less maintenance and still perform well, especially on “dry” lane conditions.
The 1990,s saw the introduction of the “reactive resin cover stock” bowling ball, and the stampede to higher scoring began. This group of cover stocks have a sort of “tackiness” that seems to grip the lane, this allows for greatly increased hook potential, and a ball that seems to deliver more energy and hitting power to a larger strike pocket. These bowling balls won’t bowl for you, however they will make a good bowler a lot better. You no longer have to be exactly precise, but rather bowl in an area.
Building on the huge success of reactive resin cover stocks are the newer “particle reactive resin cover stocks” which are even more aggressive on the lanes.
To take advantage of these new high tech bowling balls you need to check out the pro shop at your bowling center, or find out where the good bowlers in your area buy their equipment, you need to buy from someone who really knows how to fit a ball to you and your particular style of play, and then drill that ball to match.

Many surfing aficionados often wonder exactly how the board they are riding was built. The process of surfboard design and construction is surprisingly complicated today, especially when you consider that the surfboards used a century or two ago were literally boards cut from a single tree trunk.
While for centuries surfboards were solid wood, the modern era of surfboard design began in 1946, a date which marks the first fiberglass surfboard design. This early style consisted of two hollow, molded pieces with a piece of redwood running down the center for stability. In 1949, the first board with a Styrofoam core was built. This buoyant center was enclosed not by fiberglass but by thin sheets of plywood sealed with resin. The first truly modern boards were built beginning in 1958. These surfboards, designed by Hobie Alter, were produced with a polyurethane foam core and fiberglass shell. Today, nearly every surfboard design uses this mode of construction.
Typical surfboards sold today have a polyurethane core, surrounded by fiberglass and polyester resins. Often, a redwood “stringer,” or stabilizer is contained within the core. The fin of the board is made either of wood or of laminated fiberglass and resin layers. While this basic construction has remained the same for many years, the shapes and styles have certainly changed. Over the past few decades, boards have grown shorter and longer several times, with popular designs including one fin, two fins, or three fins. Today, surfboard makers continue to experiment in the search for the perfect board. Serious surfers may use as many as five or even ten different boards for different surf styles and beaches.
Although there are certainly many brands offering standardized and mass-produced boards, the highest quality surfboards are individually crafted by talented surfboard makers. Although techniques vary from one builder to another, most surfboards are built one at a time starting with the formation of the foam core. Known as a “blank,” most surfboard builders form this core in a large mold that is roughly the shape of the finished surfboard. Liquid polyurethane is poured into the mold in order to form a dense foam. Once cooled, the surfboard core is removed from the mold.
Now, the core is cut in half, from the nose all of the way to the tail, to allow for the insertion of the stringer. The purpose of a stringer is to provide stability, keeping the board from snapping in half. Glued between the two halves, the core is then clamped back together.
Now, it’s time to finish the shaping of the board. The outline is cut and then smoothed into its final shape. Some builders use computer-guided machines to do this, while many surfboard builders often use only their experienced eye to guide the shaping process. The blank is now ready to be covered in a fiberglass and resin shell. The core of the board is covered with a fiberglass cloth, and then a layer of polyester laminating resin. When done, the leg leash and fin are attached to the board. During the final finishing process, excess resin is sanded away, leaving a glossy and perfectly smooth coating.

What is Custom injection molding?
The first question that comes to mind on hearing the term Custom injection molding is what is Custom injection molding? Custom injection molding refers to the making of plastic parts for specific applications i.e. customizing the components as per the customer’s requirements.
Injection molding of Custom Plastic Parts
Injection molding is a process in which plastic pellets are melted and injected under high pressure into a mold cavity. The molded parts are then ejected, and the process repeated. The finished products can then be used as is, or as a component of other products. To do so requires an injection molding machine and tooling (often called a mold or die). The molding machine consists of a clamping unit to open and close the mold automatically, and an injection unit to heat and inject the material into the closed mold. Injection molding utilizes very high pressures and typically the machine is hydraulic or, increasingly, electric. Tooling for production injection molding applications must be able to survive under high pressure and is made from steel or aluminum. The potential high cost of tooling often drives the economics of a plastic molding application. Injection molding is an effective way to make custom parts.
The process broken down
There are three main components in the injection molding process. The injection apparatus itself which melts and then transmits the plastic, the mold, which is custom designed, and clamping to provide controlled pressure. The mold is a specially designed tool with a base and one or more cavities that will eventually be filled with resin. The injection unit melts the plastic granules and then injects them into the mold by either a reciprocating screw or a ram injector. The reciprocating screw offers the ability to inject smaller amounts of resin in the total shots, which is better for producing smaller parts. After injection, the mold is cooled constantly until the resin reaches a temperature that allows it to solidify.
Complications with Injection Molding
Injection molding complications are few and can be easily avoided by paying close attention to the design of the mold, the process itself and caring for your equipment. Parts can be burned or scorched when the temperature is too high, which is sometimes caused by the length of the cycle time which may be too long. This causes the resin to overheat. Warping of parts happens when there is an uneven surface temperature for the molds. Surface imperfections (commonly known as bubbles) happen when the melt temperature is too high, which causes the resin to break down and produce gas. This can also be caused by moisture in the resin. Another complication is incomplete cavity filling, which occurs when there isn’t enough resin released into the mold or if the injection speed is too slow, which results in the resin freezing.
Running a Custom Injection Molding Business
Custom molding business is a competitive business and to survive you should find your niche market. Most custom molders in business today have found a niche. Through experience, the molder became good at molding a particular type of part or at molding a particular kind of material, or in working in a specific segment of the marketplace. In other words, he acquired an expertise and stuck with it.

A commercial concrete floor sealer, also known as concrete floor finisher, is a resin-based, water emulsion sealing compound applied on concrete floors to protect them from corrosion and other harmful elements. It boasts a glossy hard finish and excellent adhesion properties. Commercial concrete floor sealers are most commonly used to seal the floors of commercial areas like offices, factories, and stores. The main purpose of a commercial concrete floor sealer is to deliver an economic, long lasting, and serviceable finish to commercial concrete floors.
Commercial concrete floor sealers shield the floors against dust and moisture damage. Additionally, they protect floors from the harmful effects of weak acids, salts and stains. Sealers comprising epoxies, linseed oil and various urethane based materials are used for commercial concrete floors. Commercial concrete sealers containing siloxane water repellent help to avoid spalling and the premature deterioration of floors. Likewise, for a chemical resistant surface, penetrating concrete sealers are an ideal option.
Sealing the commercial concrete floor not only protects it from everyday wear but also enhances the color of the acid stained floor. Usually, concrete floor sealers are easy to apply and quick-drying. A brush, roller or commercial spray equipment can be used for applying the sealer. A recommended first step in the application of sealers is to clean the floor with some cleaning solution. Commercial concrete floor sealers can also be used on old floors, which are affected by white stains and adhesion problems.
Concrete floor sealers like Chem-calk® 950 polyurethane sealant with tear and abrasion features are suitable for sealing concrete floors in mall areas. In the case of steel-troweled commercial concrete floors, concrete sealers with silicates and surface active agents can be applied. Some of the recent additions in the commercial concrete floor sealer market are sealers colored with quality pigments, sealers with waterproofing coating, and fiber-reinforced concrete sealers with great adherence and mechanical features.

Ok, so I keep having small pieces of plastic snap on me, so I keep fixing them until they either no longer break or no longer contain enough of the original piece to continue considering it a ‘repair’ and not a ‘full fabrication’ 
I will show you some of my favorite stuff to fix things with from around the house to parts on your helis, hell the possibilities are endless. What you need- Polyurethane casting resin (I use Max CLR, cheap and effective- look up the specs online to see what it can do!) plastic cups rubber gloves cardboard or paper for work surface (This stuff is messy and it will never come out!) Mixing cup (disposable cups of various sizes work best, you will not be able to use your mixing cup again after this, so go cheap and disposable) something to mix with, plastic knife or similar spatula-like utensil. Flat works best to keep air bubbles out of the mixture. Tinfoil or some sort of release-paper/film Something that is broken Something to grind and sand with- dremel tool is recommended Patience Carbon fiber helps…is sometimes necessary to fix thin pieces of plastic to original strength. I had to use a sliver of scrap carbon fiber to fix this link, the urethane may have been strong enough on its own, had I not reassembled things too quickly and given her a test spool-up, which promptly undid all of the work you see in the vid, but in about 10 minutes I had another batch mixed and I did the same thing only this time to be safe I ground one side of the …
