Product Description:

1. Advantages of Multi-Cavities PP Preform Mould 

.professional team:we can provide all kinds of  technical consultation service;

.advanced making machine:we have  Coordinate Measuring Machine from Italy and  NC Flat Grinding Machine,Precision Flat Grinding Machine from Taiwan,etc;

.pleasing packaging and delivery:our boss will supervise the packaging  process;

.free spare parts:we can provide spare parts which may damage for free


2. Main Features of Multi-Cavities PP Preform Mould 

.Mould plates are P20 Steel with pre-hardening process. Core, cavity and neck screw are made of S136 high strength anti-corrosive stainless steel, which is better than 48HRC.

.Mould plate is completed by one-time processing to ensure the concentricity of molding hold and guide bush, guaranteeing the compact structure of the mould. 

.Opening/closing pulling plate (material S136) adopts bearing slide type to drop the perform with reliable structure. And it is a highly integrated process of slider, pushing plate and ejection. All sliding parts surface inlaid self-lubricating copper alloys to ensure low friction coefficient and strong wear-resistant.

.The main components are consistent with various well-know foreign brands, high positioning accuracy and convenient disassembly. 

.Reasonable and quick spiral cycle waterway can get rapid cooling effect to shorten cycle time. 

.Adopting double cone positioning principle guarantees high manufacturing precision to ensure the product does appear flash, different sizes, irregular and other defects. 

.Neck screw is processed by famous brand equipment. The dimension is accurate and consistent

.Moulding part hardening makes the friction surface stable, identical and durable in use.

4. Instruction of Multi-Cavities PP Preform Mould 

We complete mould making line, from the mould's design, processing, assemblage, test to perfect mould. The mould designed by AutoCAD system, PRO-Engineer system, Solidworks system etc. 

For the mould processing, we use precision machines and CNC machine.

For the mould assemblage, we have experienced workers who has more assemblage experience. With carefully work attitude and rich experience, make our mould quality better and better. 

For the mould test, our company also make all kinds types of injection molding machine, this is our excellent, as other mould company not have this advantage for good testing. 

For PET preform mould, there are 8 cavities, 16cavities, 24cavities, 32 cavities  48 cavitied  and 72cavitied for choice. 

PET material because of its exceptional performance, are generally used two-step molding process, by the preform injection molding machine to produce a 24-hour After cooling, the internal molecular structure of their re-arranged in an orderly manner, and blowing for the next step to create good conditions, so that more excellent blowing performance products. Such as the famous Coca-Cola Company is currently using this technology.

Q:What is a mold bite
Is lousy skin grain, a lot of plastic parts surface is very thick leather grain, like a car instrument on the stage or storage battery mirrors, etc., fine grain with spark machine can play out, but do not to come out of coarse grain, you need to use chemical liquid will need mold cavity rotten into grain, also called texture
Q:What certificate does the mold major need to take an examination?
Mould CNC processing programming: in addition to individual enterprises, general stamping die designers design molds without CNC programming. While the injection mould designer is in the mould design, there are many examples of numerical control programming. In general, die designers do not have numerical control programming. The task of programming is done by a CNC programmer who specializes in programming. The programmer analyzes the tasks that need to be processed by nc machine tool, and then, according to the situation of the factory, the suitable procedure is written to the processing workshop. Normally, the program is sent to the mold manufacturing workshop within the specified folder. Mould manufacturing and manufacturing process: in the manufacturing process of mould manufacturing and the use of mould, various problems are encountered. This is especially true when a new process is enabled. Selection of machine tool, cutting tool selection, the selection of cutting parameters, the selection of cooling fluid, the feeding speed, allowance, the knife, how to position when heat treatment, etc. The problem is, how to detect, mould making decisions often need to process engineers.
Q:The difference between wire cutting and mold making
(4) test and test. Because of the characteristics of the mould and the experience of mould design, the mould must pass the test or the test pressure after assembly, and finally determine whether it is qualified. At the same time, there are some parts that need to be tested to be finalised. Therefore, there must be a certain testing period for the production schedule. (5) the machining of molds to mechanization, elaboration and automation. At present, the demand of product parts for mould accuracy is higher and higher, high accuracy, high life, high efficiency and more and more. The machining accuracy depends mainly on the precision of machine tool, the processing technology condition, the measuring method and the method. At present, precision molding grinding machine, CNC precision surface grinding machine, precision CNC wire-cut edm machine, precision continuous trajectory coordinates grinder and the use of three coordinates measuring machine is becoming more common, mould processing to the intensive development of high and new technology.
Q:What is the use of the mold collecting water
The large molds that have more water in general need to be more than a dozen or even hundreds of water from the molds. There are not so many interfaces in the cooling water. Only the water that was first placed on the mold will be concentrated on the water block, and then from the water block to the cooling water.
Q:The plastic mould automatically dies and the product drops when it falls
I can see that you are also a mould-born, and I won't say anything about the second, the pneumatic secondary roof can adjust the rhythm of the blow. Where does the product meet with the mold, and where does it hit the mold when it is scratched or falling off? Can't make way? And one way is to use both hands, also just manipulator only suck in down, one of the product is a movement up and down, but the two products are formed a time order, the speed also have won't each other parts
Q:What is the discharge in the die
Just use the electricity to get the mold in place to get the hole you need! The mould material is very hard to make use of the drill, when it is difficult to open the hole and when the precision is high
Q:What is die parting face?
For example: a plastic ball, it is of two quasi semicircle, looked closely, can see a circle line is the parting surface, if it is a big a small half sphere of clamping, can't do that most of the ball out from the mold. So the parting face should be easy to make, easy to make, low cost of making, and some of the addition of insert and exit.
Q:What is the material of hot pressing die?
Die steel must have sufficient hardness and abrasion resistance, sufficient strength and toughness. With good machining performance and good decorative pattern, it is commonly used for carbon alloy steel. Commonly used in Japan, yk-30, yellow card 55CC, which is generally used in the factory state, is better after processing.
Q:How is the die in the manufacturing industry
If you are a production company, you can buy it as a tool and sell it as a material sale. Purchase: low value consumables - molds Taxes should be paid in the form of VAT Bank deposits (or accounts payable) Sales: bank deposits (or accounts receivable) Other business income - material sales Tax payable - value-added tax Cost of transfer: other business costs Low value of the loan - molds Welcome to use the "fiscal and tax question-and-answer community" for financial advice
Q:How does the die rod work? Is it through the press?
The device in the upper module is called a push device. It is flexible and rigid, and its purpose is to remove the shock and waste from the concave mold. It is widely used because the rigid push device is strong and reliable.
