Product Description:

1. Structure of Multi-Cavities PP Preform Mould 

preform mould,PET preform mould 
single cavity with self-lock to keep less thickness tolerance 
Mould life:800K-1,500,000 shots

PET preform mould


2. Main Features of Multi-Cavities PP Preform Mould 

.Off-center Adjustment System
Off-center adjustment system can make the error of preform’s wall thickness less than 0.05mm. This system does not affect the lifetime of mold;
.Self-lock System
International advanced bi-awls fixed orientation self-locked structure has been adopted.
.Cooling System
All the water Channels in the mold’s each inner part, which make the cycle time short enough. And all the cooling channels have been specially treated to prevent them from jam;
.Heating System
Double Heating System can ensure that the impact of heating is good and quality control is credible. The Heating Band unit makes nozzles be with invariable temperature. The Heater Unit is used to heat the hot runner plate with long using life and powerful heating capacity.
.Hot Runner System
The perform mold adopt Pin-valve type Hot Runner System, such hot runner system can reduce mold’s each part’s wear & tear and maintenance cost, and also save 10%~15% electric energy;
.Hydraulic Ejecting System
The perform-doffing success ratio has achieved firm endurance and the whole perform ejecting process will become much quieter.

Q:What does it mean to pull the mold? What's going on?
There are many reasons, such as 1, block of foreign body, cleaning surface, suitable type of stripper
Q:What is the difference between a large water inlet and a thin nozzle?
1, before the gate is mould no separate parting mould also called junior die guide pin is installed, and fine nozzle is fixed mold has a separate classification that is a mould parting more than one time (at least 2 times) Generally speaking, the mouth of the water is a product which has more or less water in it, but the water mouth is the opposite! The top of the mouth of the large water mouth is A plate with A simplified and standard water outlet in the front mold 4, a lot of water mouth push board ~ ~ the water mouth is: more than a big water mouth to feed a push board. Large water mouth: a nozzle that is removed by manual or other means. Water port: a water port that is removed by hand or other means without the need of the rear sequence.
Q:Why is the mold selected for quenching?
In order to improve the wear resistance of molding parts are generally must carry on the quenching process, and achieve H RC52-57 0 in the parts of structure USES, core plate and ejector plate and plate type of components at the top of the molding or out of the plastic parts. When the bear larger unit extrusion pressure, also want to quenching treatment, made of 45 # steel parts required hardness reaches HRC40 ^ - 45. Other parts, such as guides, guides, etc., will also be hardened by means of extending their service life. Some of the complex die parts. Size is bad control. In the case of little plastic parts production, allowing the tempering treatment as a final heat treatment process, in this no longer after finishing. Some important die parts in the process of processing, should arrange the heat treatment procedure properly (annealing or positive fire, adjustment of quality processing etc. When using low carbon steel (such as 20th steel) or alloy steel (such as 38CrMoA1A) for forming parts, the surface heat treatment such as carburizing or nitriding is required. Heat treatment of the so-called steel is a process of changing the performance of steel by using different heating, insulation and cooling in the solid state
Q:What is the "KO hole" on the injection mold?
General mould, the greater the KO hole design of the KO hole, the more it but the location of the KO hole mold must be according to the plunger position of injection molding machine is used to open, or mould thimble can't top up!
Q:How to open the exhaust in the plastic mould exhaust, should notice what?
The exhaust of plastic mould should be noted Don't be too stressed out Don't overheat the plastic Don't inject too quickly Don't give the piston back too early The weight of the plastic parts should be near the device's rating
Q:What is suitable for moulding steel
Mold steel belongs to the special steel, it is the steel which makes the mould such as cold stamping die and hot forging mould. Molds are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio meters and electrical appliances. Steel mills make steel by adding special elements to steel. The mould steel can be divided into (cold making die steel), (heat making mould steel) and (plastic mould steel) 3 kinds, for forging, stamping, cutting, die-casting etc. Because of all sorts of mould USES different, complex working conditions, so the mold steel, according to the working conditions of mold manufacturing, should have high hardness, strength, wear resistance, enough toughness, and high hardenability, hardenability and other process performance. Because of the different kinds of USES, the working conditions are complex, so the performance requirements for the die steel are different.
Q:Is the stainless steel bowl replaceable in the oven?
I had been sitting in a stainless steel basin for several times, and now I wonder why I spent so much money on the molds, which was much cheaper, a ten-inch dish of ten dollars.
Q:How do you play the continuous stretch mold
Don't listen to that one, he only understands the words in the paper, he can't use it! First, the outside big circle is in pull small circle perhaps dead fixed! How high is the large circle? How much is the smaller circle? Tell me the data and contact me again!
Q:Basic knowledge of die fitter
The work of the fitter is very extensive. There are main lines, machining parts, assembly, equipment maintenance and innovation. (1) underline the parts before processing. (2) the processing parts of the mechanical method is not suitable or cannot solve the parts and all kinds of worker, clamp, measuring tool and a variety of special equipment manufacturing, such as to be done through bench work. (3) assembly of good machining parts according to the technical requirements for components, precision machinery parts assembly and final assembly, making it a complete machine. (4) the maintenance of mechanical equipment in the process of using a case of damage, failure or use for a long time to the bench after losing the use of precision parts for maintenance and repair. (5) to improve the productivity and quality of the products, the innovation and improvement of tools and processes are also important tasks for the workers. In short, the fitter is an indispensable part of the machinery manufacturing industry.
Q:The effect of mould preheating and several methods of preheating
Natural (coal) gas heating: a widely used method. Applicable to different mould shapes. The heater is made of pipes, and there are many small holes in it, and the gas is ejected and the size of the fire can adjust the air valve to achieve it. Clean without pollution, can be heated locally. The disadvantage is that it is controlled by people, and it is easy to burn the mold.
