Need good tooling design from start before machining to assembly.

Procedures :
1,Mold Flow to optimum the best injection locations in view of
- warpage for acceptable product strength
- weldlines/potential air trapped locations
2. Cooling
3. Machines size
4. Tool steels selection

For quality plastic parts with the appropriate durability, clients need to invest appropriately.

Mold vendors take the required specifications from their customers and produce a mold. This mold is then provided to the injection molding company to manufacture the parts.
If the part produced is not designed with the correct plastic materials, final products can fail in testing or in consumer’s hands.
Commonly enough, failure of injection molded parts is not an issue of bad practice on anyone’s part, but rather due to a reliance on cheap, low-durability plastic materials in order to obtain a lower cost.
For quality parts with the appropriate durability, clients need to invest appropriately.

Peoduct design by plastic injection molding process

2/2/2019

1 Comment

1) It's precision
Plastic injection molding is such a precise method that it can fabricate nearly any type of plastic part.
2) It's quick
While the speed depends on the complexity of the mold itself, generally only about 15 to 30 seconds pass between cycle times.
3) Labor Saving.
Injection molding equipment typically runs with a self-gating, automatic tool to keep operations streamlined and production ongoing, requiring minimal supervision.
4) It's resourceful.
.That's because a) only as much plastic as is necessary is used to create the part and b) excess plastic can be ground up and recycled after use.
5) Flexibility.
It's simple to change the type of material that is being produced as well as the color that the product is being produced in.
6) Creating high-strength components.
Plastic injection molding is an ideal process for industries or products where parts need to be strong
7) Good finished appearance.
Plastic injection molding is a process, for the most part, where produced parts need little to no end finishing. That's because all parts that come out of the mold are about the closest thing to a finished appearance.
8) Cheaper than plastic machining, long-term.
The initial creation of a mold can be expensive, with the cost being a few thousand dollars. But once the mold is created you can create a very large volume of plastic components at a minimal cost.
9) It's widely used.
Plastic injection molding is one of the most popular plastic producing processes.

injection mold China: clamping force

20/8/2018

.Clamping force of injection machine minimization. GREAT IDEA!

It can be slightly reduced with multi-drops (from 6 to 8 drops) hot valve gates together with by controlling in a defined sequential time respective gates of opening and closing.

A good idea to reduce cost in the long production run !

Wall Thickness Plastic Parts Design by injection mold China

13/8/2018

1 Comment

Wall Thickness of plastic products design is important.

Non-uniform wall sections can contribute to warpage and stresses in molded parts.
@ Sections which are too thin have a higher chance of breakage in handling, may restrict the flow of material and may trap air causing a defective part.
@ Too heavy a wall thickness, on the other hand, will slow the curing cycle and add to material cost and increase cycle time.

Generally, thinner walls are more feasible with small parts rather than with large ones. The limiting factor in wall thinness is the tendency for the plastic material in thin walls to cool and solidify before the mold is filled.
The shorter the material flow, the thinner the wall can be.
Walls also should be as uniform in thickness as possible to avoid warpage from uneven shrinkage. When changes in wall thickness are unavoidable, the transition should be gradual and not abrupt

Plastic Part Molding Defects: Warp (Warping, Warpage)

3/7/2018

0 Comments

Description:
The molded component is twisted, uneven, or bent shape where one was not intended. Warping is usually caused by non-uniform cooling of the mold material. Different cooling rates in different parts of the mold cause the plastic to cool differently, thus creating internal stresses. These stresses, when released, lead to warping.
Solutions:
@Ensure that the cooling time is sufficiently long and that it is slow enough to avoid the development of residual stresses being locked into the part.
@Design the mold with uniform wall thickness and so that the plastic flows in a single direction.
@Select plastic materials that are less likely to shrink and deform. Semi-crystalline materials are generally more prone to warping.

Design for manufacturability is also known as design for manufacturing or DFM in short.
In the industry of plastic injection molding. DFM is more often like”design for moldability“, as mold makers focus on the feasibility of injection molding process. A report (normally in PPT) on DFM to show customers how to optimize part design, our molding solution and potentially problem areas of your plastic parts.

It is free of charge.

Flashes in plastic injection molding (www.injectionmolderchina.com)

20/5/2018

0 Comments

Molding Flashes debug !
It occurs when a thin layer of material is forced out of the mold cavity at the parting line or ejector pins location.

Causes:-
@ worn or poorly fitting parting surface, including mold plate deformations and obstructions (grease,dirt, debris). @insufficient clamp force of which mold plates shut off are not holding sufficiently.
@ over-packing on sections, thus increasing localized pressure.
@ non-optimal molding conditions, including material viscosity, injection rate, mold temp. and runner system, etc.
@ improper venting due to poor designed venting system.

Solutions:
# ensure correctly fitting mold plates, set up the mold to seal properly, clean the machine from any obstructions, add pillar or thicken the mold plates if there is any deformation of the mold plate during molding process.
# avoid over packing
# select machine with higher clamp force #vent effectively, especially at materials joining lines
# optimize processing conditions with reducing pressure and shot size to the minimum required.

Deformation in plastic part in plastic injection molding

Plastic Part Deformation in control from START in plastic part design !?

Plastic design, mold design, plastic materials selection and injection parameters are the 4 keys in affecting final plastic part deformation. The plastic part design is dominated the others.
With uneven wall thickness and differential shrinkage at different locations:
- mold design and raw plastic materials will make up a little effect,
- injection molding parameters setting will then be more demanding for reducing deformation of parts under constant part weight and tool gating size by means of
@ lower mold temperature
@ longer cooling time
@ lower holding pressure

Tolerance in design can keep costs down in plastic injection molding

16/2/2018

1 Comment

Depending on the end use of the product, tight tolerances may not be required.
Many consumer-type products do not require anything more than standard tolerance control because the severity of failure is low.
Many designers automatically set a tolerance in the CAD drafting software and all dimensions are toleranced to that number, when in reality the product may not need such a tight tolerance.
Designers need to understand that tighter tolerances may equate to increased production costs and development costs—therefore tolerances should be as generous as possible in the design phase to keep costs down, unless they are required for proper fit or function of the part/assembly. Achieving tight tolerance may be a more expensive process, so if it not required, loosen up the tolerance a bit to reduce production costs.
