The complete injection process is called a molding cycle. The period between the start of the injection of the melt into the ‍‍mold cavity‍‍ and the opening of the mold is called the clamp close time. The total injection cycle time consists of the clamp close time plus the time required to open the mold, eject the plastic part, and close the mold again, the injection molding machine transfer the resin into molded parts through a melt down, injection, pack, and cool down cycle. A plastic injection molding machine includes the following major components as below.

Injection system: feed the raw materials into cylinder, heat up and melt it down, push the melted materials into the cavity through the spure.
Hydraulic system: to provide the force of injection.
Mold system: to load and assemble the mold.
Clamping system: to provide packing force.
Control system: to control action, cooling system.

Clamping force is commonly used to identify the capacity of the plastic injection molding machine, other parameters include shot volume, injection rate, injection pressure, screw, layout of inject bar, mold size, and the distance between tie bars. Plastic injection molding machines can be divided into several categories, besides general-purpose machines for normal plastic parts without high precision or unusual design, there are tight-tolerance machines especially for high precision parts, and high-speed machines for thin-wall parts.

A whole injection molding process includes following six steps

1) The mold closes and the screw begins moving forward for injection.


2) Filling, eject melted raw materials into the cavity.


3) Pack, the cavity is packed as the screw continuously moves forward.


4) Cooling, the cavity cools down as the gate freezes off and closed, the screw begins to retract to plasticize material for the next cycle.


5) Mold open and part ejection, the mold opens and parts are injected out by ejection system.


6) Close, the mold closes and the next cycle begins.

Could I ask you some questions if you are free?/ Are you free now? May I ask you some questions (aquestion)?

2． 请问此产品的面是否为外观面？表面做什么处理？是晒纹/抛光？

Can you tell me whether the surface of this part is a visible/esthetic one? What will we do for its

surface? Texture or Polishing?

3． 请问产品这个面可否加顶针或顶块？产品允许加扁顶针吗？

Does this part need an ejector pin or an ejector bar? Can we  add an ejector blade?

4． 这个产品的柱位我们打算做司筒。（或镶针）可以吗？

Can we add ejector sleeves or ejector pins in the boss of this part?

5． 产品的这个位置不能出模，我们打算做行位，在此面上会有分模线，你接受吗？

There's an undercut at this position and it needs a slider. It will also have a parting line on

this side, is that OK?

6． 产品里面的这个位置我们打算做斜顶或内行位，有问题吗？

We will make the lifter and (inner) slider in this position, will that be a problem?

7． 你提供的2D产品图与3D产品图不一致，请问以哪一个图面为准？

The 2D and 3D drawing you provided is not the same, can you tell me which one is correct?

8． 你提供的3D产品图有的地方没有出模角，有的地方胶位太厚，有的地方胶位太溥，这些产品问题我们可以自己修改吗？修改后会给交给你确认。

There is no draft angle in the 3D drawing, some materials are too thick, and some place are too

thin. Can we modify this part by ourselves? We will send the drawing to you for you to check after

we modify it.

9． 按你们提供的缩水率千分之五，这个模具的尺寸已经做到了模具图面要求。但注塑出来的产品不符合你们的产品图。请确认你们的材料的缩水率是否正确？

Accoring to the shrinkage one over two hundred, the mold has been done in the right dimension, butthe part falls short to your part drawing, are you sure the shrinkage is right?

10． 产品的这个位置太小，导致模具钢料太溥，能够加宽这个位置吗？

This position is too small and will make the steel material here too thin, can we widen it here?

11． 斜顶与后面的柱位空间太小，斜顶在运动时会干涉到柱子，能移动这个柱子的位置吗？

The angular lifter interferes with the boss during ejection. Please consider changing the position

of the boss.

12． 这个筋骨位胶厚太溥，而且高度偏高，注塑时很难填充这个筋位，可以增加这个筋骨位的厚度吗？

The rib here is too thin and on the high side, so it will be difficult to fill here when we do the

injection, can you inrcease the thickness of this rib?

13 你是想将此筋骨位的高度加高/减低吗？加胶的位置我们将用铜公放电加深。但减胶的位置有两种做法，1、做镶件；2、烧焊；因为镶件的底部有运水，我们简单的做法是烧焊处理，你可以接受吗？

Will you increase/decrease the material on this rib? We will use EDM if you add material, but there

are two option if you choose to decrease:1.Make inserts;2.Welding, because there is water in the bottom of the insert, is that OK?

14． 这个样板的筋骨位底部烧焦，是因为排气不良，我们可以在筋骨位的中间增加一个镶件。

This sample has been burned in the bottom because the venting is not good, we can add an insert in

the middle of the rib.

15． 重做镶件大约需要5-6天时间，你能接受吗？

It will take about 5 or 6 days to redo the insert, is that OK?

16． 产品的这个面我们已经做了晒纹处理，如果需要加胶，这个面我们需要重新外发晒纹。可能需要几天的时间

所以我们直接以铜公放电的火花纹取代你要求的纹路，你可以接受吗？

We have made the texture on this side, if we add material, it will take some days to remake the

texture by out-resourcing, so we suggest using the texture by EDM instead, is that OK?

Retaining a Slide

A slide-lock in an injection mold can hold a slide in its outward position while the mold is open. This insures that the slide will be in position to engage the angle-pin when the mold is closed. In operation, the angle-pin moves the slide away from the molded part when the mold opens. The angle-pin disengages the slide when the slide-lock is in the capture-range (K=0.02“~0.03”). The slide-lock holds the slide in position while the mold is open. When the mold closes, the angle-pin overrides the slide-lock and moves the slide left to close the molding cavity.

Cut-Off Die

A slide-lock can prevent a sheet-metal part from sticking to the underside of the stripper after the part is cut off. In operation, this example shows that the slide-lock plunger being compressed between the sheet metal and the stripper during the down-stroke. On the up-stroke, the plunger pushes the sheet-metal downward preventing it from being held against the stripper by stamping-fluid surface tension.

Back to Top

Embossing Die
	Slide-locks can lift a sheet-metal part after embossing. In operation, this example shows that the slide-lock plungers are compressed between the sheet metal and the die section during the down-stroke. On the up-stroke, the plungers lift the sheet metal out of the die section.

Back to Top

Forming Die
	Slide-locks can eject a sheet-metal part after forming. In operation, the slide-lock plungers are compressed between the sheet metal and the pressure pad during the down-stroke. On the up-stroke, the plungers push the sheet-metal part off the forming punch. For best results, the slide-locks can be located near the formed edges as shown (near the outside edges of the forming punch).

Back to Top

Notching Die

Slide-locks in a progressive die can lift a sheet-metal strip after hole punching or edge notching. In operation, the slide-lock plungers are compressed between the sheet metal and the die section during the down-stroke. On the up-stroke, the plungers push the sheet-metal away from the matrix. If any burs extend downward from the sheet-metal into the matrix, lifting the part upward prevents the burs from interfering with the sheet-metal progression through the progressive die.

Slide-Lock Pressure

The locking force of a slide-lock depends on the compression of the plunger. Greater plunger compression provides greater latching force. This example shows a SLK-25A providing 25 pound of locking force when the latch compresses the plunger all-the-way. The same slide lock provides only 12.5 pounds of locking force when the latch slides higher above the holder and compresses the plunger only half-way.

Punching Die

Slide-locks can prevent a sheet-metal part from sticking to the underside of the stripper after punching. In operation, the slide-lock plungers are compressed between the sheet metal and the stripper during the down-stroke. On the up-stroke, the plungers push the sheet-metal downward away from the stripper preventing it from being held against the stripper by stamping-fluid surface tension and gravity.

    The type of gate selected depends on many factors including: 

        Gate witness marks,
         Material Type,
         Filler used (if any),
         Tooling Costs,
         Scrap Allowance,
         and the Mold  Plates used among others.
    Small restrictive gates are preferred.  Minimal sized gates provide a small witness mark, and detaching parts from the Gate/Runner is easier.
A single gate per cavity is desired,  however,  part size and the material  used may dictate multiple gates to be used.
     Locate the gate in an inconspicuous location of the part if possible. The Gate location should be at the thickest wall of the part (flow from thick ,to thin) and the thickness of the gate should be approximately two thirds the size of the wall. 

        The gate location  and the surrounding area is also the highest area of stress in the final part.  Do not position the gate at a location that part function indicates bending  or impact strength is required.
There are two general categories  of gates:
    1.  Automatic De-gating
            Automatic de-gating includes Sub gates and 3-Plate Pin gates
    2.  Manual De-gating
            All others generally fall into the Manual de-gating category.

Correct cooling of an Injection Mold is required to produce good quality parts at an optimum rate.  All Injection Molds have some sort of cooling provision to ensure  efficient part production.  Chilled water (80-140 degrees F) is perhaps the most common medium to extract heat energy from the the mold.  Coolant lines are drilled into various plates at specific locations to provide even uniform cooling of the mold cavity steels.  

Many standard cooling components are available to provide the Mold Designer with many options to achieve the uniform cooling patterns needed for ensure quality part production.   The most common coolant line diameter is 7/16, while 5/16 and 9/16 are used less frequently.

Slide Action molds typically contain the following components:
   
Angle Pin (also referred to as: Cam, or Horn Pin)
     The function of the Angle Pin is to move (drive) the Slide attached to the "B" side of the mold.  Angles are typically 5-28 degrees from the vertical.  The angle and length of the pin is determined by the amount of travel is required for the "Side-Pull" of the part.

 Slide
       The slide can be a steel that forms a portion of the part, or it can retain core pin or other shape of core steel.  The slide usually rests upon a wear plate and retained via a gibing system.  There typically is a wear plate attached to the slide that enables the heel block to push the slide in for final locking before injection.

 L-Gibs (or Gibbing)
        L-Gibs are used to contain the slide, and ensure that the slide moves in an accurately and smoothly without any significant misalignment of the slide to the other cavity forming steels. L-Gibs and wear plates are usually Lamina Bronze.  Grease grooves are added to aid in preventing wear.

 Wear Plate
        The wear plate provides a surface that will resist wear when the slide moves over it, during the life of the mold.

 Slide Retainer
        The Slide Retainer holds the slide in the fully open position to ensure that the slide does not move until it is supposed to (otherwise, damage will result to the mold).  There are many types of slide retainer mechanisms, some are standard components.  A Ball-detent can be used as a retainer.

 Slide Lock
        Slide Locks are required to "Lock" the slide in place for injection.  The lock takes ALL the pressure off the Angle Pin during injection (the angle pin does not touch the slide during injection).  The angle of the lock is typically 2-4 degrees greater (from the vertical)  than the Angle Pin.
