Integral Insert / Liner is our unique, patented solution for sleeve cost optimization. It is single-body HPDC component made of special alloy, used as insert / lining of shoot sleeve in order to extend its in-service lifetime and decrease the frequency of shot sleeve replacements substantially.
Integral Insert / liner is a special component used for protecion of the sleeve across whole diameter and length.
It is a single body component produced using our specially developed wear resistant alloy.
It is easly inserted and replaced in the sleeve with our custom made tool.
It is compatible with all kinds of shot sleeves (even existing ones can be adjusted) and does not influence outer diameter of the sleeve.
It is highly customizable to specific customer requirements.

Envelope
HTS Integral Insert / Liner + Envelope
Shot sleeve is bored to form an envelope and a special integral insert / liner that covers the whole lenght of the sleeve, gets inserted into the envelope
This way sleeve / envelope never comes into direct contact with molten alloy, so sleeve replacements are completely avoided. Insert / liner is the only component that needs to be replaced
Insert / liner gets replaced very quickly, in case of smaller machines it can be done directly on the machine, while in case of larger ones, there is a special replacement tool we provide.
When using Integral Insert / liner the cost of envelope occurs only at the start of implementation.
As seen below, the difference in usage compared to conventional shot sleeve is that cost of envelope occures only once, at the implementation of integral insert solution and then, for each replacement only the insert / liner needs to be changed with a new one, while envelope remains unchanged.
HTS Integral Insert / Liner is made using our specially developed alloy that allows us to bring nitration layer hardness up to 1.250 Hvickers. This is 25% more than what can be reached when using traditional 1.2243/H11 or 1.2344/H13 made shot sleeves. Such difference in hardness translates into substantially (up to 55%) longer lifetime than conventional sleeve.
Nitration layer hardness (Hvickers)
Replacing Integral insert takes considerably less time than replacing whole sleeve.
Smaller integral inserts can be replaced directly on die casting machine, while for bigger ones we supply a special tool that makes insert replacement quick and easy.
HTS developed tool for integral insert replacement.
Using Integral insert / liner to protect shot sleeve you save up to 30% on cost of sleeves, because the amount of sleeves required to complete a series is reduced substantially. In some specific cases, savings can reach up to 60%.
Customer savings on Ø140 x Ø340 x L1006 sleeve
| DIMENSION | RANGE (mm) |
|---|---|
| Inner Diameter | 70 – 180 (larger diameters available on request) |
| Length | 400 – 1400 |
Based on the type of the sleeve, different mounting options can be used
Integral inserts are made using forged or rolled tool steel blocks produced in EU.
Most often used grades are special HTS developed alloy or 1.2343/H11.
Based on specific customer need, other steel grades can be used.
