As an important moving component, linear guides are an indispensable component for many machines. So many customers need to install them by themselves after purchasing linear guides. What should they pay attention to when there are no technical personnel present? Let’s talk briefly today. You can consult our technical staff for specific operations.

The first thing to note is not to remove the slider from the guide rail at will. Normally, we ship the slider and the guide rail together, which means that the slider is of good quality, because there are balls inside the slider. If you take it out without paying attention, it may cause the balls to slip. If the ball is lost, the slider cannot be used. Generally, our manufacturer will be equipped with a slider push-off device to assist in removing the slider and reduce the occurrence of ball falling off.

 

In addition, disassembling the slider during assembly may cause dust and dust in the environment to fall in. After reinstalling, the motion may be stuck and the accuracy may be reduced, which is not worth the gain.

 

So before the formal installation, we must first carefully clean the installation location, remove burrs, dust and other dirt on the work surface, and keep the work surface smooth and tidy. In addition, it is necessary to apply anti-rust oil to the linear guide rail to prevent rust from affecting the normal function and performance of the product in future use.

Linear guide rails are usually fixed with bolts. Each model has a recommended bolt model. Customers are also asked to use the recommended sizes.

 

When fixing the bolts, be sure to tighten them and keep the track and the workbench close to each other without shaking. After tightening them all, drive the hole cover into the assembly bolt to keep it on the same level as the top surface of the linear guide rail.

 

There are some technical requirements for the assembly and installation of linear guides. We recommend that our customers find relevant technicians or consult the manufacturer for technical support during organization and installation.

A rewinder machine is a machine that is used to wind a roll of material, such as paper, film, or tape, into a smaller roll or into a specific shape. There are several types of rewinder machines, including surface winders, center winders, and coreless winders, each of which operates slightly differently.

 

 

 

In general, a rewinder machine consists of a series of rollers or drums that the material is fed through, as well as a drive system that rotates the rollers or drums to wind the material onto a spindle or core. Some rewinder machines also have additional features, such as slitting or cutting systems, to cut the material into specific lengths or widths.

 

 

 

 

To operate a rewinder machine, the operator typically loads the material onto the machine and sets the desired winding parameters, such as the winding speed, the width of the material, and the size of the finished roll. The machine then winds the material onto the spindle or core, using the drive system and rollers or drums to control the tension and position of the material. Once the roll is complete, the operator can remove it from the machine and prepare it for use or storage.

 

A filling machine is a piece of packaging machinery that fills products into containers such as bags, pouches, bins, or bottles. The types of filling machines differ depending on the products being filled, which can include liquids, pastes, granules, and powders.

Filling machines can be manual, semi-automatic, or fully automatic. Automatic filling machines can guide, organize, fill, and release bottles in an automatic bottle packaging line, such as a filling, capping, and labeling line.

When choosing a filling machine, you can consider things like:
The type of container you want to fill
The size of the container you want to fill
How many containers you want to fill
How viscous the liquid is
Whether you need a manual, semi-automatic, or fully automatic machine

Whether the machine meets FDA health and consumer protection guidelines

 

When choosing a filling machine, you can consider things like:
Product characteristics, Container, Production capacity, Filling accuracy, Automation level, Maintenance, Hygiene, Operator skill, Budget, After-sales support, Compliance.
Here are some other things to consider:
Container size, shape, and material
Bottle compatibility
Integration with other machines
Future output
Regulations
Container size, shape, and material
Vacuum-level filling machine: Can fill most rigid plastic or glass bottles with thinner, free-flowing liquids
Volumetric filling system: Likely to be required for jars, flexible bottles, or pouches
Automatic bottle fillers: Might not be the best choice for containers with non-standard lids or caps
Bottle fillers that grip from the side: May not work well with very wide containers
Regulations
Liquid filling machines for the food industry must meet the FDA's health and consumer protection guidelines

 

Gravity Filling Machine
Gravity fillers are typically used to fill thinner, foamy liquids. Gravity liquid filling machines work by pumping bulk supplies into holding tanks, which are set above valves that are operated pneumatically. Each valve is set for a specific fill time to enable free-flowing liquids such as water and inks to fill containers using gravity.

Piston Filling Machine
Piston fillers are also ideal for many different liquids. Piston fillers allow for accurate and fast fill rates, along with versatility as they can handle many types of products. They’re frequently used to fill highly viscous products such as pastes, sauces, chunky fillings, batters, and icing. Piston fillers are also often used to fill liquid products in pastry bags and other similar containers.

how piston filling machines work
This type of piston filler is best suited for viscous products that are paste, semi paste, or chunky with large particulates. These piston fillers are built to meet food grade standards and can also handle various chemical applications.

Examples
Heavy sauces, salsas, salad dressings, cosmetic creams, heavy shampoo, gels, and conditioners, paste cleaners and waxes, adhesives, heavy oils and lubricants.

Advantages
This lower cost conventional technology is easy to understand for most users. Fast fill rates are achievable with fairly thick products. Warning: this technology is nearly obsolete with the advent of servo positive displacement fillers.


Pump Filling Machine
Pump fillers are also used for many types of products. Their combined versatility and accuracy makes them ideal for filling liquids of low, medium, or high viscosity levels. The pumps used in these machines can include gear pumps, rotor pumps, cavity pumps, and lobe pumps, among others depending on the application. In addition to pump systems, there are many options for valves and fittings.

Molten Filling Machine
Molten fillers are uniquely designed to work with products that require hot-filling before cooling and hardening once filled. The products that molten fillers are most frequently used to fill include candles, petroleum jelly, deodorants, glycerin soaps, and lip balm.

Pressure/gravity Filling Machine
Pressure/gravity fillers are similar to gravity fillers in their operation, but their use of pressure to fill containers makes them more suitable for thicker liquids.

Net weigh Filling Machine
Net weigh fillers are used to help ensure that every container has the same amount of product across the line, which makes them ideal for filling bulk quantities of liquid products or products of high value whose wastage can be costly.

Inline Filling Machine
Inline liquid filling machines fill containers along a single file line across a conveyor system. These machines are designed to fill liquid and semi-liquid products of various viscosities and in many different container shapes and sizes. Small to medium-sized businesses use these models most frequently to maximize filling efficiency.

Rotary Filling Machine
Rotary filling machines can move containers through circular stations, each of which is intended for a different function such as filling, capping, and sealing. Many industries use these machines for a wide range of products.

The performance and strength data measured by tensile testers are important in the selection of design and materials, purchase and sale of products, development of new products, quality control, and safety of equipment.

During the research stage of product development, tensile testing is crucial in choosing the most appropriate materials. A tensile test machine can verify whether candidate materials pass the required strength and elongation requirements for a certain product.

In the metals industry, tensile testing provides an opportunity to discover new alloys, their qualities, and the possible uses they might have. This can lead to improved materials, which are beneficial to both manufacturers and end users.

The use of a tensile strength tester in the quality control of products is also crucial. It provides manufacturers a way to identify whether there are problems in their manufacturing line. It also ensures that what they deliver to customers is safe, of high quality, and adheres with industry and international standards.

The cost of not complying with industry standards may not only be monetary. At worst, it could involve human cost. Performing regular tensile testing usually costs far less than the consequences brought about by using inappropriate materials or sale of substandard products. Therefore, carrying out reliable and accurate tensile tests should be a priority.

Extruder is a kind of plastic machinery, is commonly used in the modified plastics industry, widely used in the polymer processing industry and other production and processing areas. Extruder can be divided into single screw extruder and twin screw extruder. They have different working principles and applications, and each has its own advantages and disadvantages.

 

First of all, there are many differences between single-screw extruders and twin-screw extruders in terms of plasticising capacity, material conveying method, speed occasion cleaning and so on. As shown below:

 

1. Different plasticising ability: single screw is suitable for plasticising polymer extrusion and extrusion processing of granular materials; the shear degradation of polymer is very small, but the material stays in the extruder for a long time. Twin-screw mixing has good plasticising ability, short residence time in the extruder and is suitable for powder processing.

 

2. Different material conveying mechanism: material conveying in single-screw extruder is drag flow, solid conveying process is friction drag, melt conveying process is viscous drag, the friction coefficient of solid material and metal surface and viscosity of melt material largely determines the conveying capacity of single-screw extruder. Material conveying in a twin-screw extruder is positive displacement conveying. As the screw rotates, the material is forced forward by the intermeshing threads. The capacity for positive displacement conveying depends on the proximity between the screw edge of one screw and the screw grain of the other screw. Large positive displacement conveying can be obtained by using a close-meshing counter-rotating twin-screw extruder.

 

3. Cleaning for different speed occasions: The speed distribution in a single-screw extruder is clearer and easier to describe, while the situation in a twin-screw extruder is more complex and difficult to describe. This is mainly due to the engagement area of the twin-screw extruder. The complex flow in the engagement area makes the twin-screw extruder have the advantages of full mixing, uniform heat transfer, high melting capacity and good exhaust performance, but it is difficult to accurately analyse the flow state in the engagement area.

 

4. Different self-cleaning: twin-screw extruder shear speed, because the engagement zone of the spiral rib and spiral groove of the speed of the opposite direction, the relative speed of fast, can scrape off any attached to the screw on the accumulation of material, has a good self-cleaning effect, the material stays for a short period of time, it is not easy to occur local degradation. Single screw extruder does not have this function.

 

In addition to different working principles, they have different application areas. Twin-screw extruders are widely used in the physicochemical modification of matrix resin, such as filling, reinforcing, toughening, reaction extrusion, etc.; single-screw extruders are mainly used in the field of pipes, plates, sheets and profiles.

 

Application examples of twin-screw extruders: glass fibre reinforcement, fuel-resistant pelleting (e.g. nylon 6, nylon 66, polyester, polybutylene terephthalate, polypropylene, polycarbonate, etc.). , high filler pelletising (e.g. PE and PP filled with 75% CaCO3), thermosensitive material pelletising (e.g. PVC and cross-linked polyethylene cable materials), concentrated masterbatch (e.g. filled with 50% colour powder), anti-static masterbatch and alloy cable material pelletising (e.g. sheathing and insulating materials), cross-linked polyethylene pipe pelletising (e.g. hot-water cross-linking masterbatch), thermoset plastics mixing and extruding (e.g. phenolic resins, epoxy resins and Powder coating), hot melt adhesive and polyurethane reaction extrusion granulation (such as EVA hot melt adhesive and polyurethane), K resin and SBS de-volatilisation granulation.

 

How to choose the model of twin screw extruder?

 

In today's rapidly developing plastics processing industry, twin-screw extruder has become one of the indispensable equipment. However, a variety of models on the market is dazzling, how to choose the right one for you?

 

Firstly, let's introduce a few common models: GS20, GS35, GS50, GS65, GS75 and GS95, which represent the specifications and performance of the extruder and focus on different materials and applications.

 

The GS20 model is suitable for small batch production and R&D trials and has a small output and discharge capacity. It is suitable for processing some special high-temperature, high-viscosity materials, such as special plastics or rubber.

 

Model GS35 is suitable for small and medium-sized enterprises and small batch production, with relatively high output and discharge capacity. It is suitable for processing some common medium-viscosity materials, such as polypropylene and polyvinyl chloride.

 

GS50 model is suitable for medium scale production with higher processing capacity and discharging capacity. It is suitable for processing all kinds of medium-viscosity materials, such as ABS, PET and so on.

 

Model GS65 is suitable for large-scale production with higher throughput and discharge capacity. Suitable for processing most of medium and high viscosity plastic materials, such as polycarbonate, polyamide, etc.

 

The GS75 model is suitable for extra large-scale production, with very high output and discharge capacity. Suitable for processing a wide range of low, medium and high viscosity plastic materials, including polyester, polyamide, polyethylene, etc.

 

The GS95 model is suitable for ultra-large scale production, with the highest output and discharge capacity, and is one of the most advanced extruder models on the market today. It is suitable for processing plastic materials of all viscosities, including high temperature and high viscosity engineering plastics.

 

Therefore, choosing the right twin-screw extruder model for you needs to be decided according to the required output, processed materials and processing requirements. It is recommended to know your production scale, product requirements and expected return on investment before purchase to ensure that you choose the most suitable extruder model for you.

 

In addition to the above mentioned model selection, but also need to pay attention to some other factors, such as equipment stability, energy consumption, maintenance and so on. Because these are also key factors affecting production efficiency and quality.

 

When choosing the model of twin-screw extruder, we need to do fine thinking and consider various factors comprehensively. By choosing the right model, you will be able to complete the production of plastic products efficiently and stably and achieve greater business success.
