open nozzle

open nozzle include pin point gate and direct gate.The open nozzle also can divide into two parts.The one is drop gate ,the other one is adiabatic bin in nozzle.

To the direct gate of open nozzle
This kind of nozzle can keep the high temperature and prevent from freezing.The direct gate with smaller pressure drop should be well deliver the hold pressure .Besides,it can be used in injecting large-scale,long process,thickened wall and deep cavity components.The direct gate of open nozzle is suitable for replacement of heat-sensitive plastic and colouring plastic .Because this style of nozzle is easy to clean that we recommend to process the secondary use of plasic material.

To the pin point gate of open nozzle
The gap of heat insulation is made up of nozzle and the hole in manifold.Pin point gate will decrease the wire drawing and flash.It apply to amorphous plastic and the plastic of slower crystallization such as PP,PE and thermoplastic elastomer.You'd better not select the pin point gate of open nozzle to inject the material of heat insulation and the plastic material which need change the colour.

These information od open nozzle i told stop here.I hope it will help you!

hot runner system moldflow

Moldflow is software of plastic injection that has huge resources.Its level of difficulty in thchniques is higher and it is hard to command in a shorttime.Hot runner system moldflow will be conductive to producing a perfect or inerrant products.The hot runner system moldflow functions as following,

Moldflow functions include

• injection molding process simulation analysis
• injection mould cooling system simulation analysis
• structural stress analysis of plastic part
• molding shrinkage analysis of plastic part
• warpage analysis of plasic part

I focus on the hot runner system moldflow in this topic.In the former function,it include pouring system and mold filling analysis.The aims of pouring system analysis is to make sure the reasonable location and size of the runner ,the location and number of sprues.The hot runner system moldflow (molding filling analysis) is in order to know the reasonable shape and size of plastic parts and also to confirm the thickness of plastic part.Hot runner system moldflow will put the knit-line and air sac in a place where the appearance and structure permitting to get the best parameters of pressure and speed of injection.

Anole hot runner video

What factors effect bottle preform hot runner selection? I will make a brief introduction of what should pay attention to when do bottle preform hot runner selection. We should take these factors into consideration: the quality of product, design of product, plastic material, mould, cycle time, gate, nozzle, runner, temperature controller box, and performance of injection machine. After having a clear idea of these factors, we can do proper bottle preform hot runner selection
1. Product weight: different product have different requirement for hot runner. It is the most important factor when do bottle preform hot runner selection
2. Plastic material: different plastic material have different processing course. It will effect bottle preform hot runner selection.
3. Mould: How many cavities? How the nozzle ranged? What material the injection mould process?
4. Gate: as to pin point gate, the tip must have the function of melting plastic and closing the gate, so that it can balance the heat. The valve gate nozzle should use machine to close the gate.
5. Nozzle: the nozzle could be selected by size, temperature distribution, material and maintenance. The nozzle will effect bottle preform hot runner selection
6. Runner: Using hot runner could save the material, make the surface more smoothly, leave out the process to remove the resin.
7. Temperature controll: each nozzle must connect with a temperature controller. It will effect bottle preform hot runner selection
8. Performance of injection machine: It could install mould, have enough mould clamping force.
10. Product design: Generally, the product design is finished earlier than mould. In order to ensure the smooth surface of product, we should take the product design into consideration. Product design decide bottle preform hot runner selection.
All the elements have influence on bottle preform hot runner selection. We should do bottle preform hot runner selection according to these factors.

injection molding solution|hot runner solution examples

Today we list several examples of injection molding solution that we successfully solved for our customers that is difficult but commonly used recently.
injection molding solution example 1
name :lampshade
size:DIA25mm×850mm
material:transparent PC
weight:1.25kg

hot runner solution difficult injectin points:the material is PC,the viscosity is too high and very difficult to injection,what's more,the out looking requirements is very strict.and also.as the product is very big,it is very difficult.at the first,Anole refused to accept this order.because it is too risky to do it,basiclly ,PC is an engineering material and it is not easy to deal with.secondly,the products size is too big but the wall thickness is so small.and besides.and then YUDO also refused to take this order after analysis.but as Anole provide much cheaper price for this injection molding solution,and the customer wanted to have a try.finally.we choosed special pin needle for the valve nozzle as valve hot runner system is the only method to satisfy the requirements.
injection molding solution example 2
name:bump
size:1250×550×450mm
material:PP
weight:3.11kg
hot runner solution:wiht 4+2 injection points valve gate nozzle, because it needs really strict requirement for the surface outlooking.
injection points:4nozzles,also need a main runner nozzle as we can't let the heat from injectin machine to the manifold go away.temperature controller:insert type which can be changed very easily.price of this whole hot runner system include controllers is:US$15000
injection molding solution example 3
in the next article we will keep talking different hot runner solution for injection molds.and if you have any questions about injection molding solution,please contact me as a techinical communication. service3@anole-hot-runner.com
 

Hot runner plastic material used for injection molding,this article will show the plastic for injection molding machine.the plastic material,the main content is the plastic material choice for hot runner.

At the beginning for design products,inorde to choose using plastic,most designer did't take the mould into consideration.If it possible,the plastic choice for hot runner can make the mould processing more easier is the best.
The forming with low contractibility rate like PS,ABS,PC,The precision of the dimension can be easier make.but the forming with hign contractibilily rate like PP,PE,POM plastic material can be hardly to make the precision of the dimensin.(mould tolorance is the forming tolorance's 1/6)
ABS have the big viscositty ,the flowing liquid can easy to flow in to the gap,but for PA,POM.Even if the gap is very small,the liquid would easir to entrance.
The temperature is low when forming,can be easy to form and the the forming cycle time is quick,like the PS material.but the high temperature when forming ,the cycle time would be slow.
The material can not be easy to deteriorate and anysis like PS,PE,PP when forming,woukd bot affect unstable quolaity with large quantity production.In the opposite position,if the material can be easy to deteriorate and anysis without the strict forming requirement(mould can controll the forming requirement in precision),the large quantity can not take into effect.And this hot runner is in trouble if in this position.

Realized the hot runner platic material function is more important for the injection moulding processing.

A successful hot runner mold application project needs many links to safeguard. And most important two technical factors: plastic temperature control and plastic flow control.
1. plastic temperature control
 It is great importance of plastic temperature control in hot runner mould applicaion.The product quality question originate directly from hot runner system temperature inaccurate control in many production processes. such as hot needle type injection product bad quality question, when valve type runner needle closure difficult question, polymorphism cavity die has the components packing time and the quality inconsistent question and so on. If possible should choose multi-regions to control the warm hot runner system separately, increases the use flexibility and strain capacity.
2. plastic flow control
The plastic should flow balance in hot runner system. The runner must simultaneously open to fill various die spaces synchronization. Must balance design running size of family mould which components weight phase difference.Otherwise will present some components sufficient mold guarantee presses insufficiently, some components actually sufficient mold guarantee presses excessively,edge oversized bad quality and so on questions. The hot runner size design must be reasonable. The size too small the sufficient mold pressing power lose oversized. The size too large,hot runner volume oversized. plastic resident time excessively long in hot runner system,material performance will damage causes the components formation cannot satisfy the operation requirements.

   I will introduce solutions to hot runner gate block in this article. Generally speaking, the gate block is result from the low temperature of plastic melt in gate. In addition, the structure of nozzle, the quality of thermocouple, the range of coil heater, the installation will also lead to hot runner gate block. Following are some reason and solutions to hot runner gate block.
    Open gate: reasons and solutions to hot runner gate block
1. Reason: the temperature is too low in gate. Solution: Decline the gate cooling speed. Check if the plastic is suitable for the nozzle. Check if the heat insulation bore is large enough.
2. Reason: the temperature is too low in nozzle tip. Solution: Decline the contact area between the tip sealing gluing and mould.
3. Reason: The heat is not enough in gate. Solution: incline the diameter of heat insulation cavity and decline the tip length. Check the tip and gate are in the same direction.
4. Reason: The impurity block the gate. Solution: Separate the manifold and clear the impurity away.
    Besides, there is another hot runner gate block and solutions to hot runner gate block are followed.
    Valve gate: reason and solutions to hot runner gate block
1. Reason: the valve is too short or out of shape. Solution: change the valve
2. Reason: the gate was damaged. Solution: check if the valve is too long.
3. Reason: the leakage of hydraulic or pneumatic cylinder. Solution: Check the seal devices.
4. Reason: the valve was improper touch with the gate. Solution: decline the gate temperature and lengthening the valve.
5. Reason: the dwell time is too long. Solution: shorten the dwell time.
