Heat Sealer is a consistent tool used to perform sealing on flexible packaging products and other thermoplastic materials using pressure and heat by maintaining high temperatures. A heat sealer is used to measure the heat seal performance of composite films, plastic films such as PP, PE used in packaging different food products such as milk powder, instant noodle, food, washing powder, and drugs.
Prestos Laboratory Heat Sealer is widely used in packaging and plastic industry. It is a machine used to seal products like thermoplastic materials, packaging material using heat. Heat sealing helps to join two different materials one of which consist of thermoplastic layer.
Heat Sealing is the process of sealing one thermoplastic material with another using pressure and heat together. The method of sealing utilizes a constantly heated sealing bar or die to apply heat to a specific contact path or area to weld the thermoplastic together. The laboratory heat sealer is used for multiple applications like heat seal connectors, films, thermally activated adhesives, foil sealing or plastic ports.
The temperature of the machine is adjustable. It is a fully pneumatic model that has a digital display and based on microprocessors.
The heat sealer is equipped with two jaws i.e. lower jaw and upper jaw. Both the jaws of the machine can be heated separately with different temperatures and controllers. Hence, it is possible to maintain the temperature of both the jaws separately. It is possible to enable or heat one heater at a time, and it is also possible to switch off one heater in between while performing the test. The instrument is used to seal the plastic sample at the predetermined heating temperature.
The conical mandrel bending tester is widely used to examine the properties of a coating. It examines the resistance to cracking or detachment from its substrate along with the product elongation during the test. Conical Mandrel is a method to determine the flexibility and sticking properties of coatings when the test specimen or material subject to bending stresses.
Prestos Conical Mandrel Bending Test instrument is a laboratory apparatus widely used to bend coated panels over a cone shaped mandrel to judge the elasticity or resistance of a coated paint or finish to cracking; detachment or elongation from as per ISO 6860 and ASTM D522 standards. The conical shape of the testing instrument allows the deformation of the panel and examination of the elasticity range of a coating.
The test procedure is commenced by bending the test specimen around a conically shaped metal bar. The laboratory equipment is used mainly for coated and painted panels.
Conical Mandrel is widely recommended to test the resistance of paint, varnish, coating to evaluate crack resistance or detachment from a metal panel. The apparatus consists of a steel mandrel of a specific length and tapering of a specific diameter. The machine is equipped with a graduated scale right on the clamping bar that depicts the mandrel diameter at which failure has occurred.
Hence, the percentage of elongation is calculated by adding the measurement of mandrel diameter to the thickness of the panel used. Conical mandrel helps to detect the common failures of coating that show flaking and cracking after bending.
The Conical Mandrel Bending Tester is a compact, robust instrument made of enameled steel which is suitable for table-top use. The conical mandrel and the pivoted pressure roller running parallel to the surface of the cone are made of stainless steel. The clamping device is equipped with a cam lever which ensures a rapid and uncomplicated change of specimens. The mandrel bending test is a commonly used testing method for assessing the flexibility and the adhesion properties of coatings when these are subjected to bending stresses.
Prestos Industrial LabMuffle Furnace Digital Computerisedis specially designed and manufactured for the developing fields of agricultural, medical research industrial, metal treatment, ash determination and wool industries. The device evaluates the ash percentage of a test sample that provides vital information on properties of the material. The device has an elegant design and is convenient to install. The instrument can be used for various applications for example, for mold heating and organic & inorganic tests. The thermal-shielded furnace is cost-effective and energy saving.
The equipment calculates the ash percentage same as the index of added mineral loading. The test is performed by weighing the specimen and then burnt. The burnt sample is calculated easily. The test specimen is torn into small pieces and then placed again to take the weight. The accurate test result can be obtained by performing three tests by reporting minimum, maximum, and average weight.
Prestos Profile projector is a cost effective solution for angular measurements and for Digital linear. The machine also has a built-in DRO.
The basic use of Profile Projector in PET & Preform Industry is to identify an edge or point of the shadow of the PET Bottles in order to measure the length of the PET or Preform from this particular point. By expanding the image via profile projector, the operator can easily decide that from where the edge or the point of the shadow starts. Profile images are also used to take important decisions to fulfill various measurement purposes like it matches the size of the bottles with standard size to evaluate whether a part of the bottle is designed correctly or not.
FEATURES

Environmental Stress Cracking Resistance tester is a unique test cabinet designed to detect the change in the physical characteristics of the plastic material and to ascertain the actual working life of test samples at environmental stress. It is important resin property caused by tensile stresses.
Environmental Stress Cracking is the brittle failure of a polymeric material from a combination of stress and environment. The frequency of failure depends on the material properties, the environment conditions, its level and type of stress under certain conditions of stress, and in the presence environments like wetting agents, soaps, detergents, oils. Blow molded polyethylene container exhibit involuntary failure by cracking at stresses substantially below those that would cause cracking in the absence of such environments.
Test methods of ESCR are clearly described in various standards that can be used to calculate the environmental stress- crack resistance of plastic containers.
Prestos Environmental Stress Cracking Resistance is designed as per ASTM D 1693 to evaluate the effect of environment on blow molded plastic containers. In the presence of few materials like oils, soaps, detergents or wetting agents containers may reveal a mechanical failure by cracking. A similar effect is observed under various circumstances of tension and cracks that occur at a substantially lower level of stress in the absence of such conditions.
Prestos Environmental Stress Cracking Resistance is widely used to measure the cracking resistance of plastics due to environmental stress, which is necessarily the abstract of various parameters. It is influenced by the design of the container, molding conditions, treatments during and after production and other related factors that affect this. This test procedure helps plastic manufacturers to separate and identify the effect of the related factors on stress crack resistance of the container.
The machine is supplied with standard accessories like digital temperature controller, cutting die, foils and glass tubes.
Prestos round cutter is mainly used for precise circular cutting to check the grammage of samples. The cutter cut out the specimen of 100 cm2, which is exactly equals to 1/100thof a square meter accurately and rapidly. The result is in grams when multiplied by 100 gives the GSM directly, i.e. gram per square meter. So we can say that,
GSM = Sample Weight in Grams x 100
GSM round cutter is equipped with 4 knives. By rotating the knob quarter a turn, the cutter will provide you the sample of 100 cm2.
To operate the instrument, place a piece of specimen between the cutting board and sample cutter. Now release the safety catch and exert light pressure on the hand wheel. To cut the specimen in accurate shape and size, rotate in clock-wise direction with light and even pressure. This will help you to get the circular sample with smooth edges.
