The Biggest Challenges to Plastic Injection Moulding Industry!

With the advancement in Plastic Moulding Technology and the development of complex geometric shapes required to be manufactured in a variety of plastic resins designed for high-performance parts, mould has become the weakest link in the value chain.

Many designs fail to fully consider all the dynamics of the moulding process because of the lack of insightful data or non-availability of materials that can meet the demands of the process. This results in approximations in tool design and sub-optimal product quality.

Tool steels continue to be the most widely used and accepted materials not only for the larger tool but also for cores, inserts and cavities. While tool steels are useful for their properties and lower cost, there is a tendency among mould designers to ignore other high-performance materials, mainly due to cost optimization. This results in making serious sacrifices to mould life and performance, and also lower quality consistency of the part.

Inserts or cavities made from steel have poor thermal conductivity making them ineffective as they are unable to extract heat quickly from molten plastic, leading to uneven cooling, resulting in porosity and shrinkage defects. Inserts are effective when they can extract and dissipate heat quickly, allowing the process to cool faster and more uniformly across the cross-section.

QTi® Copper Titanium Inserts and Cooling Plates

QTi® Copper Titanium Inserts and Cavities provide the most optimum combination of Thermal Conductivity and Wear Resistance, making it the most preferred material for Plastic Dies and Moulds.

Copper Titanium exhibits and maintains high hardness even at elevated temperatures, which make it suitable to be used for a wide range of plastics resins and complex geometries. Copper Titanium is a 100% Beryllium Free, High Conductivity alloy which can extract heat quickly, allowing the plastic to solidify quickly and reduce warpage and cooling Time.

Improve Productivity with Copper Titanium 

With faster heat extraction and quicker solidification of plastic resin, there is a reduction in (hold time) cycle time, and thus improve productivity.

Die Casting Industry Challenge – Rejection!

With the ever-growing demand for aluminum die casting parts and increasing competitiveness in the market, Aluminum Die Casters are constantly looking to optimize and reduce costs of manufacturing to meet customer cost targets and improve profitability.

Rejection rates in the casting industry are high.  It is estimated that most aluminum foundries across the world have rejection rates between 3% to 7% sometimes even more. This is many times more than the 3-digit ppm levels demanded by the customers.

Such high rates of rejections directly affect profitability.  Of the many reasons that can cause casting rejections are poor plunger life and premature failure, insufficient heat extraction from the castings, leading to porosities and other defects.

QTi® Copper Titanium Core Pins and Inserts

Core pins and inserts in dies are subjected to high thermal and mechanical stresses in GDC, LPDC & HPDC Casting process. Core Pins made of steel can withstand the wear but are unable to extract heat quickly due to poor thermal conductivity, which results in uneven shrinkage and porosity in the casting.

Copper Titanium Core Pins and Inserts provide an excellent combination of high thermal conductivity and good wear resistance. QTi Inserts are much harder than other competing copper alloys and exhibit thermal conductivity up to 5 to 10 times greater than steel pins. High hardness of Copper Titanium alloy provides excellent wear resistance. This significantly increases the life of the pin, and dramatically reduces casting rejections.

QTi® alloy provides excellent corrosion resistance and has inherent lubricity and galling resistance. QTi® pins can be coated with a super-hard PVD coating thus increasing their surface wear resistance even more, without any compromise on the thermal conductivity. The coated pins and inserts can be used in very demanding applications and the integrity of the casting can be maintained and rejections reduced.

QTi® Copper Titanium Chill Block and Vents

Copper Titanium Chill Vents are 100% Beryllium free and exhibit excellent thermal conductivity. Chill-Vents are commonly attached to Steel Die Casting molds used in casting aluminum and magnesium. The primary objective of the Chill Vents is to exhaust residual hot air from inside the die cavity to outside during feeding of molten metal into the die.

If the hot air is not exhausted, it will be entrapped in the molten metal leading to gas hole defects. Copper Titanium Chill Vents are designed such that, it allows the exhaust gases to escape and solidify the molten metal before it flashes outside the mold cavity.

Advantages of using Copper Titanium Core Pins, Chill Blocks and Vents
