Injection Molding Chillers

Injection Molding Chillers

The working principle of the injection molding chiller units:

After the plastic pellets are injected into the mold after heating and melting in the injection molding machine to condense, the mold is opened to eject the molded plastic workpiece.

In the continuous production process, the chilled water system of the chiller is required to cool the mold to shorten the plastic condensing time and improve the dimensional accuracy of the workpiece. 

Molding quality and surface quality, this is the working principle of injection molding water chillers, injection molding water chillers generally use water-cooled box chillers.

If the chiller is applied to the cooling of molding molds of plastic processing machinery, it can greatly improve the surface finish of plastic products, reduce the surface marks and internal stress of plastic products, make the products do not shrink or deform, facilitate the demolding of plastic products, and accelerate product shaping.

Thereby greatly improving the production efficiency of the plastic molding machine;

chiller system basics

Chiller system basics

·       What is the principle of an Injection Molding Chiller?

A chiller performs on the principle of vapor-compression or vapor absorption closed loop.

Thus, the heat transfer takes place, the refrigerant evaporates, changing from a low-pressure fluid into a vapor.

While the Injection Molding Water Temperature of the process coolant decreases.

The refrigerant then moves to a compressor, which executes multiple functions.

·       What are the kinds of a Chiller?

        There are two kinds of a Chiller.

        They are:

  • Compression Chillers
  • Absorption Chillers

  What is drooling in Water Cooling System For Injection Molding?

When nozzles are pushed away from the mold after injection, molding has been processed out.

 Thus, the drizzle of plastic from the sprue gate occurs.

Hence, this drizzle of plastic is usually called drooling.

Moreover, it is caused by residual pressure stored in the sprue and runner.

·       What is plasticizing in an Injection Molding Machine?

The plasticizing capacity is the proportion of injectable molten plastic adhesive.

Thus, that can be made in unit time.

Moreover, this affects the proportion of the molded article that can be made.

·       What is meant by backpressure in an Injection Molding Machine?

BackPressure in an injection molding is often described as:

“The defiance of the screw to recover as the metering section pushes molten plastic via the non-return valve to the front of the screw.”

However, when this point came, the screw will stop revolving.

General Plastic Manufacturing Mold Cooling

·       How essential is back pressure in an Injection Molding Machine?

However, a little back pressure is significant.

Indeed, it helps.

Thus, the accurate size pipe is large sufficient to breathe well.

As well as small sufficient to produce a high exhaust flow.

Moreover, steps in the exhaust mechanism also produce harmful pressure waves.

Thus, that move back to the cylinder and assist empty the cylinder of those gases.

Mold Chiller

·       What is the transfer position in an Injection Molding Machine?

This is the length of the injection molding appliance controller.

Thus, the screw moves to reach the component’s desired transfer point.

Hence, this is the position where we switch from speed control to pressure control.

Subsequently, this is generally at the point where the part is 95-99% full.

·       What is the switchover position in an Injection Molding Chiller?

The switchover position is the ram position where the injection position switches to the packing part. 

However, the cushion length is the distance from the switchover position to the farthest place that the end of the screw can reach.

·       What is mold temperature in Injection Molding?

For injection-molding processing of PTT melt, and Injection Molding Water Temperature Control,  recommend being between 232–260°C and 88–121°C, respectively.

·       What is tonnage in an Injection Molding Chiller?

The “tonnage” is the calculation of energy needed to keep the tool closed during the injection.

Thus, this energy is the main component in determining the injection molding appliance size needed for producing the equipment.

·       How do you calculate tonnage in Plastic Injection Molding Chillers?

The foremost step in calculating accurate clamp tonnage is to measure the surface area of the part.

However, this means achieving the space’s square inch area by multiplying the length by the width.

Moreover, if it is a multi-space mold?

Then, multiply the number by the number of cavities.

·     

·       How do you modulate air bubbles in an Injection Molding Machine?

In contrast, use a heat gun or something familiar.

Then as you gently heat the area of the component where the bubble is formed.

Thus, the state of the bubble should change.

So, if it is a gas bubble?

The gas will heat up and expand.

Moreover, it raises the surface and often will pop as the part surface gets smooths.

How To Calculate Btu/hr For Chiller?

How to convert the hp and btu of the chiller? The conversion relationship of the cooling capacity unit is as follows:

1 kcal/h (kcal/hour) = 1.163W, 1 W = 0.8598 kcal/h;

1 Btu/h (British thermal unit/hour) = 0.2931W, 1 W = 3.412 Btu/h;

1 USRT (United States cold tons) = 3.517 kW, 1 kW = 0.28434 USRT;

1 kcal/h = 3.968 Btu/h, 1 Btu/h = 0.252 kcal/h;

1 USRT = 3024 kcal/h, 10000 kcal/h = 3.3069 USRT;

1 horse = 2.5 kW (for air-cooled units), 1 horse = 3 kW (for water-cooled units)

Description:

When “hp” is used as a power unit, it is expressed by Hp (imperial horses) or Ps (metric horses), also known as “horsepower”, 1 Hp (imperial horses) = 0.7457 kW, 1 Ps (metric horses) = 0.735 kW;

·       What causes a cold slug in Portable Chiller For Injection Molding?

 A tiny irregular area on the component is caused by an improperly heated piece of plastic attached to it.

Moreover, a curly pattern is caused by a slow injection velocity, which assists the material in proper cooling too rapidly.

·       What material are injection molds made up of?

Plastic injection molds are generally made from hardened or pre-hardened steel, aluminum, or beryllium-copper alloy. 

However, steel molds are expensive.

 But are often suggested because of their high stability.

·       How thick is an Injection Mold?

The minimum thickness of an injection molded component varies from 2mm to 4mm.

 Thus, components with regular thickness assist the mold cavity in filling more accurately.

Since the molten plastic does not have to be pushed through differing limitations as it fills.

·       How do you set specifications of an Injection Molding Chiller?

  • Set injection velocity from slow
  • Fixed screw revolving velocity from low
  • Set mold open/close velocity slowly at first
  • Set injection proportion from a short position.
  • Set prolonged pressure holding time of injection molding appliance at first
  • Set a long cooling time at first.

·       What are the functions of the clamping unit during the Injection Molding Process?

The functions of the clamp unit are:

  • to grasp and close a mold,
  • generate force, open the mold,
  • discharge the components,
Figure 1 Injection Molding Chiller

Figure 1 Injection Molding Chiller

·       How do you calculate clamping force in an Injection Molding Machine?

Clamping force is often calculated in the following ways:

  1. Empirical FormulaClamping force (T) = clamping force constant Kp * product projected area S (CM * CM).
  2. Empirical Formula 350bar*S(cm^2)/1000.
  3. It is calculated using CAE software.

·       What causes jetting in an Injection Molding?

Jetting occurs mostly when the melt temperature is too low, and the stickiness of the molten plastic becomes too high.

They are thereby ascending the resistance of its movement through the mold.

Moreover, when the plastic comes in contact with the mold?

So it is cooled rapidly, and the stickiness is increased.

Figure 3 Jetting in an Injection Molding Chiller

Figure 3 Jetting in an Injection Molding Chiller

·       What are the advantages of Injection Molding?

Advantages of Injection Molding are:

  • Rapid production and highly effective:

 Injection molding can produce a remarkable amount of parts per hour. 

Thus, velocity varies on the intricacy and size of the mold.

Hence, anywhere between 15-120 seconds per cycle time.

  • Low labor expenses:

Injection molding is an automated method.

However, the majority of the procedure is executed by appliances and robotics.

Thus, which a sole operator can modulate and administrate.

Moreover, automation assists in descending manufacturing expenses.

As the overheads are notably reduced.

  • Design elasticity:

 The molds themselves are pointed to too high pressure. 

As a result, the plastic within the molds is squeezed harder.

Thus, it allows for a large amount of detail to be imprinted onto the part.

Hence, to produce a complex or complicated design.

  • High-output manufacture:

A lot of components can be manufactured before the tooling requires to be retained.

  • Vast material variety:

 There is a wide variety of polymer adhesives to choose from.

 However, different plastic materials can also be utilized simultaneously.

 For instance, TPE can be over-molded onto PP components.

  • Low scrap prices:

 Injection molding generates very tiny post-production scrap relative to typical producing methods.

Thus, any waste plastic comes typically from the sprue and runners.

Moreover, any unused or waste plastic can be reground and recycled for future use.

  • Capability to include inserts:

However, metal or plastic inserts can be include molded.

  • Good color management:

Components can be produced in any needed colors.

Thus, with the use of master-batches or compounding.

  • Product Stability:

 Injection Molding is a repeatable manufacturing process.

However, in other words, the second part you create is going to be similar to the first one, etc.

Thus, this is a significant benefit when producing high tolerances and part durability in high proportions.

  • Descend finishing wants:

 There is often very little post-production work needed.

Thus as components generally have a good finished look upon discharge.

  • Increased Strength:

 It is feasible to add fillers in the molding matter.

However, these fillers decrease the density of the plastic while it is being molded.

Moreover, it can assist add greater strength to the completed component.

·       What are the disadvantages of an Injection Molding?

Disadvantages of an Injection Molding are:

  • High tooling expenses and long set up lead times:

 Up-front expenses are high due to the style, assessing, and tooling needed. 

Firstly, there is the initial creation and prototyping.

Then the design of a prototype mold tool to produce copies of the component in proportion.

Lastly, and only after massive testing during both steps, you can finally get injection mold a component.

  • Part design limitations:

Components must be created with injection molding consideration and must follow the fundamentals of injection molding.

For instance:

  • Prevent undercuts and sharp borders as much as possible
  • Use regular wall thicknesses to avoid inconsistencies in the cooling process resulting in issues like sink marks.
  • Draft angles are recommended for better de-molding.
  • Small runs of components can be expensive:

 Due to the intricacy of equipment, and the need to rid the appliance of all previous material before the next product can be produced, the setup time can be too long.

Therefore small runs of parts have typically always been thought of as too costly to injection mold.

·       Why is hydraulics used in an Injection Molding Chiller?

Injection Molding Chillers have a hydraulic mechanism.

Thus, that must give reliable execution through many years of constant, around-the-clock production cycling.

Moreover, there is also a requirement for energy control sub-circuits.

Thus, to keep the nozzle against the sprue of the mold and to keep the mold closed.

·       Why are Injection Molds so expensive?

An injection mold is the most costly component of the appliance.

Moreover, it can dramatically ascend prices for small component runs.

However, the main elements that affect the cost of an injection mold are:

  • the size and complexity of the part,
  • the matter used,
  • the number of parts being produced.

·       What polymers are used in an Injection Molding Machine?

Generally, plastic injection molders use thermoplastics.

However, regular polymers used by molders are:

  • Acrylonitrile Butadiene Styrene (ABS), 
  • Polyethylene, 
  • Polycarbonate, 
  • Polyamide
  • Polypropylene.

·       Is Injection Molding Chiller a promising career in 2020?

 Yes, a career in Injection Molding is a valuable option because it pays well.

Moreover, it offers a broad extent of employment chances.

The business can also be very supportive and might mean little or no student liability.

Injection Molding Chiller positively recognizes those who want a profession that doesn’t need staying at the desk daily.
