Thin wall molding is actually defined as molding the parts having wall thickness 1 mm or less than that. Speed plays most important role for the high profit in the field of thin wall injection molding. Faster filling and higher pressures are required to drive molten thermoplastic material into thinner cavities at a sufficient rate to prevent freeze off. For this machine equipped with accumulator to realize high speed injection and single cylinder injection system, especially suitable for high speed injection, with low inertia and high response speed is required.
SINO HOLDINGS GROUP is extensively experience in the field of thin walled injection molding and has manufactured super advanced mold and molding machine involving to meet the match today and beyond. Our high speed machine can reach 2.5 sec of cycle time to produce 4 cavity thin wall box of 0.4 mm wall thickness. Not only mold and machine we offer whole production line in cost effective way.
But the fact is, thin wall molding is very difficult to deal with.Much many thing are to be considered while designing tool for thin walled injection molding.
1: To withstand high injection pressures gate inserts of hardness greater than 55 are typically used .
2: Manifolds should have external, not internal, heaters. Valve gates, if used, must be non-restrictive and built to take high pressure.
3: Venting is critical and can be facilitated with vented core pins and ejector pins,While not usually necessary, some processors have sealed the parting line with an O-ring in order to pull a vacuum on the cavity for quick gas evacuation.
4: Nonlooping cooling lines should usually be located directly in the core and cavity blocks to help keep the mold surface temperature as consistent as possible.
5:When gating directly onto a thin wall with a sprue, pinpoint, or hot-drop, use gate wells to reduce stress at the gate, aid filling, and reduce part damage when degating.
6: The mold cooling system design must be optimized so that heat is extracted quickly. Just having thin walls on a part is not enough to get fast cycle times.
7:Any build up of residue across the venting surfaces will result in part quality issues especially on multi cavity moulds.

How to make sure that the fan balance mold with balance injection?
The key point for the fan blade mold is the very even injection gates and equal thickness. Injection runner design, cooling water design and moldflow analysis play vital roles in fan molds manufacturing, also the mold temperature controlling are very important. Like the table fan blade mould, 16 inch diameter, fan weight around 150 gram, three blades mould, we will design one tip hot runner nozzle with three injection points instead of direct core on the center of fan, the fan centre location will be inserted with cooper for for short cycle time, 6 groups of water channels with 3 groups of water channels followed the fan shape. Injection sprue bush is DME standard with cooling water around. And when we test the mold, the mold linked with cold water with 10 degree. The total cycle time is 35s, with plastic shaft inserts and the unbalancing weight is less than 0.4 gram.

5) The cycle time is around 8 to 10 seconds
6) Hot runner: Anole pin point gate system
7) Mould delivery time: 60 working days.
Mould difficulty:
The testing tube mold core inserts are verythin and long, that makes it easy deformation under high speed and highpressure injection. The tooling concentricity and precision control isextremely important. Also the assembling should be in very correct position.0.1mm mould tolarance would make product thickness tolarance over 0.7mm.Thenormal tolarance should be around 0.1mm. Like thin wall mould, testing tubemould also is a one time successful mould. If it faild, we need to purchase newcore inserts and re-tooling them. For testing tube mould, you should give theorder to professional testing tube mould maker like SINO MOULD.

SINO Mould is a professional mold manufacturer in designing and making plastic PCchair mould. We produce around 150 sets chair molds for one year, including PC transparent plastic chair mold, plastic rattan chair mould, PP chair mould and so on. With accumulation of so many years of PC chair mould production, now SINO has a mature technology and experience.
During the daily production, below is some issues required special attentionfor plastic PC chair mould:
1. Product scratch
PC material is very hard. if the mould steel hardness is not high enough; it will be easy to have the scratch problem. So usually for PC chair need good steel with high hardness and could also make nitriding on the mould surface which can increase the surface hardness to avoid the scratch problem.
2. Not good transparency
Mostly the PC chair mould will use transparent color, but I believe many people have met the feedback from the customer of complaining about the transparency. You can choose oil temperature instead the water temperature which can better solve the problem.
3. Silver mark on product
If the product surface has the silver problem, it means that the material is not dried enough, mostly it needs around 6-8 hours to make it dryer at around 100 degree temperature
4. Cycle time
Some customers need short cycle time, but as you know for the plastic PC chair mould, the thickness is thicker comparing to the normal chair, so the cycle time is longer than usual chair. And you can make the gate size bigger for easy material flowing.
.
If you are looking for the plastic PC chair mould, pls come to us for further information.
Welcome inquiry!
