Importance of Modern Specialized Power Press in Bottling Food and Beverages

Bottling and capping in this industry

Most foods and beverages are packed in bottles fitted with a metallic caps. Popular brands such as Coca cola, Pepsi, beers and other beverages have long be packed using metal sealed bottles. In addition, pharmaceutical products stored in the glass bottles also utilize the top covering to effectively seal the container.

Bottling and capping in this industryUse of power press in making metallic bottle caps

Power press machine is part of a larger manufacturing unit made up of the die, the blank material and the accessories for feeding the material.

The press supplies a heavy force to the punch which squeezes against the die and workspace to produce the desired shape. Punches and dies are replicas of the product to be made.

Metallic bottle tops are inherently made by punching using the power press. A flat sheet steel materials is specially printed to match the brand be packed. Normally, one sheet will have 24 to 48 prints. The sheet is then passed to the device.

The device rotational motion is converted to reciprocating motion that pushes the punch against the die. This effectively forms the shape and also shears it off from the sheet. In one process, up to 48 products can be pressed and formed. Due to the rapid cyclic movement of the machine, very many bottle tops are made with a minute.

In addition, the machine is also used to develop lids used to cover and seal many packed foods. These lids have special formations which can be produced by punches and dies.

Though there are different types of this machine, the most common are the Gap frame and straight side types. The Gap frame assumes a C shaped structure where the dies are put. Since there sides are open, the die can be accessed from three sides. This machine handle high loads (250 tons) and is less costly

Since the backside is open, wastes and scrap can be easily discarded and this makes it suitable for mass production of caps and other punched products.

Critical parameters that must be achievedThe straight side type is widely used for inline mass production. It has two vertical arms on the sides. It has a strong housing on the top part that house the crankshaft. They have crankshaft and pulleys that change the type of motion.

Trends in utilization of metallic caps in the industry

Trends in utilization of metallic caps in the industryWith the increasing number of foods, cosmetics and pharmaceutical industry requiring metal and plastic caps, the market is expected to rise gradually in the next 5 years. The use of metallic caps is however facing stiff competition from the cheaper plastic that contributes to over 80% of all the closures. In 2013, the closures market accounted for US$ 40 billion and this is expected to rise to US$ 43Billion (5.3%). US market closures consist of 80.6 % plastics and 9.8% metals. However, with the negative environmental impacts associated with plastics, the metallic closures are expected to take a larger portion.

Produce Top Quality Rings and Other Jewelry Using Light duty Lathes

Introduction

Jewels have been used from time memorial for beautification and as precious gifts passed from one person to another. They are common among celebrities, famous people and even the ordinary folks as they bring a sense of class, elegance, luxury and happiness. They are manufactured from expensive durable materials such as diamond, gold, platinum, silver and bronze.

Due to their small size, complex shape and need to conserve the expensive materials, jewels must be made using special machines to produce high quality and good dimensional stability to ensure that customers are satisfied with them.

They must also have good aesthetic appeal and be durable. They must therefore be machined to perfect smoothness and flatness.

Precision jewel cutting using light duty lathes

Most rings are cast into cylindrical shapes and later machined using lathe and mill turns. They are also manufactured from rolled flat bars though this is not common for expensive products.

Due to the precision required, the production volumes are very low. In addition, most jewels are customized according to the client requirement which differ due to different physical dimensions e.g. size of fingers and neck.

Precision jewel cutting using light duty lathesLight duty lathe machines are used to fabricate most of these rings. The material is mounted on a chuck and various machining operations done. Turning of the internal surface is done to create an internal diameter that fits on the finger while outside diameter is turned to the specified size. Facing is done on the two opposite ends to smoothen them.

In addition, other processes such as drilling, tapping, chamfering and polishing and also done using this machine. A combination of these cutting operation results to the formation of the product. For example, chamfering gives the ring a wedge like edges while knurling results to a rough surface. All these operations are performed on light duty machines fitted with a small six jaw chuck to hold smaller work pieces without affecting the surface.

Contractors specializing in fabrication of many custom items have to make numerous rings that differ in design. This is achieved by using CNC machine. The jewels are automatically made by adjusting the tools and feed. In addition, these devices have the capacity of not only performing the turning, facing and other conventional lathe work but can also mill and perform cylindrical grinding.

The lathe allows a wide number of finishing operations to be done on the ring and jewels. In the lapping operation, the ring is rubbed continuously against another surface with an abrasive liquid between them. This removes a very tiny layer and smoothen the ring.

These machines also have low power consumption and are very efficient. They are compact, durable and have excellent functionality.

Importance of Sheet Metal Machinery in Containerization Process

Containerization in International Transport

International and local transport has grown considerably due to globalization and internationalization. There has been a global increase in dependency on commodities manufactured from low wage countries such as China, India, Africa and Asian nations. This has driven the demand for better shipment.

The invention of containership by Malcom Mclean’s in 1956 was perhaps the most important innovation in the transport sector. Bulk and sensitive commodities are packed and sealed in strong durable steel or aluminum boxes. These were then loaded on trucks, ships and trains for transportation.

Containerization in International TransportThe shape of the container allows easy stacking on top of each other. Since they are manufactured from high strength materials and locked, they are intrusion free. They also have identification number allowing for easy tracking via GPS and RFID.

Essential Parts of a Container

Standard containers are manufactured from steel or aluminum. Their shape, sizes are standardized to allow easy handling and transport.

Steel containers are 20, 30 or 40 feet long, width of 7 and 8 ft and 8, 8 ½ and 9 feet high. The side and end walls are manufactured from paneled sheets. The frame is specially designed to withstand weight of other stacked containers on top. One end has door hinges, panels and locking bars.

Essential Parts of a ContainerAluminum types are made of steel frames while the sides, front, back, roof and bottom are made with high strength durable aluminum.

Machines used in container manufacture

The container manufacture process utilizes a great deal of sheet metal machinery. First they are cut to their specific dimensions using the shearing machine. This device is sturdy and has the capability of cutting heavy gauge plates in a guillotine manner.

Square, rectangular and round grooves are then made on the flat materials using a specially designed heavy duty press brake. The machine is fed with material and it forms the square corrugations.

Machines used in container manufactureThe roof panels are made pressing using a specially designed press brake machine. This device punch presses the plate against the die to form the intended shape.

Roof PanelsThe floor frame is then made by cutting the plate using a shearing machine and these are folded using a press brake machine. This machine folds the material forming a U shaped bracket. A series of these brackets are welded to form a very strong base.

The door, sides and other parts are also fabricated by cutting the plates and square tubes using shearing equipment, folding the sheets using press brake and welding the parts. Fastening holes are also drilled on all parts.

Quality issues in sheet metal working

The containers must be made from good quality materials that don’t rust or corrode when exposed to harsh sea environment. The joints and other parts must be properly sealed to protect the commodities being transported.

Rising containerization process in international trade

The container market has continued to grow rapidly. In 2012, the global container fleet was 32.9 million TEU and 34.5 million TEU in 2013. This growth is expected to continue due to their global acceptance and high demand.

Produce Air Conditioning Systems Using Sheet Bending Machine

Introduction

Air cons (AC) are widely used in residential, commercial and industrial systems to actively pump out heat and maintain a predetermined temperature and humidity. They create an artificial environment which suitable for machines, human and agricultural produce.

Air conditioning systems fabrication

Most modern house and industrial buildings comprise of many rooms that need HVAC (heating, ventilation, air conditioning system). Instead of using a separate split AC for each room, all the rooms are fitted with ducts and vents and one system is used to control multiple rooms. HVAC system regulates temperature and humidity and creates a fresh environment.

This ducted system is made up of numerous square or round pipes made from light aluminum of stainless steel sheets. They span the entire house and connect to a central duct that aerates the room.

The ducted HVAC systems showing pipes and their layoutRole of bending machines in fabrication of these systems

To manufacture these pipes and ducts, sheet bending machines are used to fold light and heavy gauge sheets. These machines are therefore found in contractor’s fabrication labs where folding sheets constitute 60% of all fabrication process.

The sheet material is cut at the required position and then fastened on the equipment. This device then folds the sheet to the required angle (normally 450 to 900 for most AC applications).

To perform a series of perpendicular and angular folds on the same work piece, these devices utilize a back gauge and specially formed dies. The back gauge accurately positions the metal sheet so that the bend is put at the precise location. This allows precision and accurate fabrication of multiple folds on the same work piece.

Successive folding of the pipesSpecial features

To fabricate folds fast and effectively, this equipment must allow continuous and precision folding of these tubes. Light and medium sized bending machine are applied in the operations since the ducts must be light in weight but durable.

Modern CNC types are becoming common. These allow accurate and precision feed, easy clamping, bend monitoring, folding as well as automatic calculation of the back gauge position based on the angle of bending. They have high ramming speed and are suitable for high throughput industry.

For small jobs on residential and commercial areas, smaller devices with less tonnage are used. These are versatile and flexible and allow folding of smaller work pieces to different angles and shapes.
