How to make a good crate mould ? To make a good crate mould, you need to know the technical points and the quality points of a crate mould as follows.
crate mould quality points:
long life
high speed performance
air venting solution in the crate’s handle area ...... crate mould technical points: How to make a crate mould long life running?
choose the correct steel for mould base and mould main steel. For example, if you need to make a 4 cavities crate mould, then you need to make to use a pre-hardened steel with HRC bigger then 33 for mould base. You have to choose the correct steel or material for the durable mould components.
make the correct harden treatment to each steel piece and make the steel hardness controlled, you can not make it too hard.
the moving area or guiding system of crate mould must be very precise machining processed. Any hand working on it is not acceptable.
if the plastic crate is one-time using, some of the molding company, they use recycled material to make the injection. Then we have to consider about this 2 points. A. how to be sure the small iron piece and the pebbles will not damage the cavities and cores. B. how to avoid the small iron piece and the pebbles enter into the cavities? How to make a crate mould with high speed performance?
Good plastic material filling system, you need a very special hot runner system, because if you need to molding a durable plastic crate, then you need to use low MFI HDPE, such like MFI=4 or even MFI=6……
You need to make the cooling the best optimal effect, for durable plastic crate mould, you need to use mold-max on the molding area with excellent cooling water channel design, for one-time use crate, you need to use tempering steel with excellent cooling system designed….
You need the high speed injection molding machine to run it, the screw RPM should be bigger then 350. in the world, now most of the crate manufacturers they use an accumulator to increase the melt and injection speed.
Plastic crate mould design also is very important, it is better to use a mechanical system onto the crate mould ejection, in this way, you can make the ejection action when the mould opening. Of course, maybe your machine can work with the 2 hydraulic acting in the same time, then you can do the ejection when the mould opening.
For all kinds of mould, the high speed running is based on the mould is précised machining, the movement parts with accurate guided…otherwise, there is none possibility for a mould high speed performance.
plastic crate mould’s handle area venting solution: this is an important issue, as because when the crate was loaded and the people carry the crate, the 2 handle area will be the biggest force focused. If on the mould, this area’s air venting is not perfect, there will be a very obviously jointing line. The damage are always come from this line.
SINO MOULD is the leading crate mould manufacturer in the world, we has developed more than 2000 sets various crate moulds such like, bottle crate mould, fish crate mould, fruit crate mould, bread crate mould......Especially we have done the 2 and 4 cavities crate mould and 4 cavities stacking mould. It is the first set of 4 cavities crate stacking mould in China. It is suitable for high speed injection, and the speed can approach 42s. We can say, we are the top crate mould manufacturer in the world.
Our question are:
do you need a high production performance crate moulds?
do you have the automatic ejection function problem in the 4 side collapsible core cola bottle crate mould?
do you want to try a 4 cavity crate mould with the dimension 400x300x150mm with the cycle time 32 seconds?
do you want to use the recycled plastic material to molding the one-time using crate?
do you need the folding crate mould with stacking mould design ?

Constant technological improvement, technological innovation makes SINOPK the industry leader in PET Preform Mold. By offering the top quality solutions of PET PET Preform Molding to the market, SINOPK has won high praise from the market. It is because we know how, and we do what should be done.
PET Preform Mold multi-cavities mould design improvements.
SINOPK has more than 15 PET Preform Mold designers, we had the technical meeting by each week in the past 6 years, in the technical meeting, we improved to our ready made mould structure and develop higher cavities nr. PET Preform Mold, from 32 to 64, to 72…up to now, we have successfully offered 128 cavities PET Preform Mold and will continues to develop 160 cavities in 2010 year.
PET Preform Mold valve gate injection system R&D.
The hot runner system of PET Preform Mold is one of the key points, SINOPK has a very special PET molding valve gate system which can avoid material leakage...it can say one of the best PET hot runner system in world.
PET Preform Mold cavities, cores and screw neck…components material selection.
We have special selection on the components material, and also do different harden or surface treatments. We use Stavax S420 for cavities and cores and DIN 1. 2083 for screw necks inserts…
PET Preform Mold components machining process.
From 2008 to 2010 May, we have invested more than 3 millions tooling machines from Europe and Japan which are especially for PET Preform Mold manufacturing. All the components of the mould will be made accordingly to our 2D prints tooling drawings, on the the drawing, there are tolerances, tooling process, material hardness…all the details. When the parts on the machines, it was measured to be sure the dimensions are meeting our tolerance. Before the components moving to assembling workshop, the QC department will make one more time measuring to be sure the dimensions are meeting the drawing's tolerances.
PET Preform Mold’s components are interchangeable.
Due to the high precise machining and rigorous dimensions controlling, in our PET Preform Mold all the same parts realized interchangeable, and for so many components which are same in different moulds, we kept them as the stocks for faster delivery time and prompt services to our customers.
PET Preform Mold injection molding speed.
We considered the mould running speed from the mould design, such like injection system, guiding system, ejection system and cooling system. In one cycle time, for example 28 seconds, the cooling time take 12 seconds, for this reason, we have considered to make the cooling outside of the mould by one vice cavities group, on these vice cavities, we used chilling water on it. By this way we can reduce around 10 seconds for each cycle.
PET Preform Mold security system.
We have designed the electronic eye on the PET Preform Molds to be sure that if there is some preform has not drop down, the mould will not closed. Also there is stroke switches on the mould to be sure the ejection return strokes are correct. In this way, we kept sure that the mould will be long life running.
PET Preform Mold mass production simulation.
Before the moulds shipment, we take at least 8 hours mould mass production speed running on our especial PET injection molding machine, to be sure that there will be none problems when the PET Preform Molds arrive our customer's workshop.
PET Preform quality:
1. Water connections consolidated at the bottom of the mold, eliminating the potential for water marks on preforms. 2.Variety of stack designs and surface finish options to allow each application to be optimized to meet customer's specific needs. 3.Special programs available when tighter than industry standard dimensional and/or weight tolerances are required 4.Lowest cavity-to-cavity weight and dimensional variation as a result of best-in-class manufacturing machines and processes
