Q17:Is The Anodized Parts Conductive?

Anodizing is actually not conductive. Moreover, the thicker the film layer, the higher its impedance.

Q18:What is the difference between aluminum profile anodizing and natural oxidation?

The difference between anodizing and natural oxidation of aluminum profiles is mainly due to the thickness and compactness of the oxide film produced. In addition, the former film thickness can be controlled.

Q19:New Die Casting Tooling Acceptance Content

When the new die-casting mold is in place, because there is no corresponding understanding of all aspects of its performance, it is necessary to confirm the following content during acceptance.
>Is the mold number clear and correct?
> Mold size?
> What is the diameter of the material cylinder?
> What is the eccentricity under the mold?
> What is the spacing of the ejector holes?
> What is the size and spacing of the tie rod holes?
> Mold cavity error value ≤ 0.1mm (check the indentation around the cavity)?
> Surface roughness Ra≤0.4μm?
> There are no damages, scratches or cracks on the surface of the cavity?
 > Can the thimble and slider be free from jamming?
> The movable and fixed mold core is 0.02~0.06mm higher than the mold base?
> Is the arrangement of the ring holes on the mold base, top plate, thimble fixing plate and mold foot reasonable and convenient?
> Are the cooling water inlet and outlet marked clearly?
> Does the cooling water mold end interface match the specifications of the company’s common water pipes?
> Does the hydraulic cylinder mold end interface match the specifications of the company’s common oil pipe interface?
> Does the supplier provide tie rods and top rods?
> Does the supplier provide core spare parts?
> Does the supplier provide spare parts drawings?
> Does the supplier provide the material certificate and heat treatment report?

Q20:Your price is very high and i can get lower price from other supplier.

First, You can always get some lower price from some suppliers in China. There is no lowest price in China at all. There is only much lower price one by one.
Of course, if you could bear various kinds of bad problems and invalid commitment of cheaper productions. Their price is cheaper $ 1 than us and you can earn 10000 USD on 10000 pcs parts. But you will lose more than 10000 USD, even more lose a faithful customer if it happened a mechanical mishap occur. At the same time, I don’t think you can get more higher efficiency of the supply when you get a price which is lower 0.5-1 USD because price elasticity depends on different service.
Finally, you are an expert in the filed, if they can give you an offer which is even lower than the cost. What will you think about it.
What you will get is what you paid for.
You can call me if you have any questions ,we will reply you as soon as possible!

Q27:Types of Dies

Dies are classified as: single cavity, multiple cavity, combination and unit dies.
A single cavity die requires no explanation. Multiple cavity dies have several cavities which are all identical. If a die has cavities of different shapes, it’s called a combination or family die. A combination die is used to produce several parts for an assembly. For simple parts, unit dies might be used to effect tooling and production economies. Several parts for an assembly, or for different customers, might be cast at the same time with unit dies. One or more unit dies are assembled in a common holder and connected by runners to a common opening or sprue hole. This permits simultaneous filling of all cavities.

Q28:Casting Dies and their Construction

Die casting dies are made of alloy tool steels in at least two sections called fixed die half and ejector die half. The fixed die half is mounted on the side toward the molten metal injection system. The ejector die half, to which the die casting adheres, and from which it is ejected when the die is opened, is mounted on the moveable platen of the machine.
The fixed die half of the die is designed to contain the sprue hole through which molten metal enters the die. The ejector half usually contains the runners (passage ways) and gates (inlets) which route molten metal to the cavity (or cavities) of the die. The ejector half is also connected to an ejector box which houses the mechanism for ejecting the casting from the die. Ejection occurs when pins connected to the ejector plate move forward to force the casting from the cavity. This usually occurs as part of the opening stroke of the machine. Placement of ejector pins must be carefully arranged so force placed upon the casting during ejection will not cause deformation. Return pins attached to the ejector plate return this plate to its casting position as the die closes.
Fixed and moveable cores are often used in dies. If fixed, the core axis must be parallel to the direction of die opening. If moveable, they are often attached to core slides. Should the side of a die casting design require a depression, the die can be made with one or more slides to obtain the desired result without affecting ejection of the casting from the die cavity. All moveable slides and cores must be carefully fitted, and have the ability to be securely locked into position during the casting cycle. Otherwise, molten metal could be forced into their slideways causing a disruption of operations. Although slides and cores add to the complexity and cost of die construction, they make it possible to produce die castings in a wide variety of configurations, and usually more economically than any other metalworking process.

Q29:How do I know what process is best for my needs?

There are several ways to tell what type of die casting or molding process is best for your needs, using several criteria. See Minghe’s General Die Casting Design Data Sheet for more information.
