INJECTION MOLD STEEL DESIGN TIPS

What Steel Should You Use When Building Your New Plastic Injection Mold?


Low Cost Injection Mold from China

Plastic Injection Mold

Your company is about to invest in an injection mold to manufacture a plastic part. That is, you’re ready to write the purchase order once you decide which molder has quoted you the best value for your dollar. You want the lowest price, the lowest injection mold maintenance, AND the highest product quality. Right? Yet, how can you tell what you’re really buying when one supplier quoted $3000 and another quoted $13,000? They both saw the same blueprint! It’s probably true that both molds could produce good quality plastic parts.

Injection Mold Scenarios

Buyers should consider two scenarios: quick machining steel/low production quantity versus slower machining steel/high production-high quality. Quoting molds is often an “assumption game.” The more the customer can define what they want, the fewer variables enter into the quote. The customer’s goal is to get apples-to-apples quotes from each supplier, and this isn’t always easy.

One variable in quoting the injection mold is the quality of steel to be used. Total Solution Plastic typically quotes high quality tool steel unless the customer specifies otherwise. We do, however, build tooling from all grades of material such as prehard steel (P-20), hardened tool steel (S-7,H-13,O-1,A-2,etc.), aluminum, or stainless steel.

Prehard: P-20

P-20 is the most popular and versatile injection mold steel. It is used for all sizes of machine-cut injection mold, and does not require post machining heat treatment. No heat treatment eliminates the finish machining and grinding operations which are necessary because of the dimensional changes which occur in heat treatment.

Prehard can be chrome-plated or nickel-plated for wear and corrosion resistance, if needed. However, we typically do not recommend P-20 steel if the production quantity is high (+500,000) or reinforced plastics are to be used. The trade-off is usually less moldmaker labor ($) versus longevity of the injection mold (time).

Hardened Tool Steel: H-13, S-7

This steel renders a fine combination of toughness and strength. The steel is mostly furnished in the annealed condition and must then be heat treated after the mold is finished. The steel hardens to about Rockwell C 46 – C 54. Hardened tool steel is used when a steel is needed for molding reinforced plastics, or when a large production quantity is anticipated. Hardened steel also takes an excellent polish, therefore it is used for clear parts such as lenses.

Stainless Steel: 420

Stainless steel is frequently used when corrosion or rusting may be a problem. Rusting of waterlines or the mold due to condensation can be very costly because of the extra maintenance and frequent polishing. Stainless 420 must be heat treated. It has outstanding dimensional stability in heat treatment and therefore, the mold needs very little finishing and correcting after heat treatment. This steel also takes a high luster polish.

Three variables enter into the calculation of a mold’s price: the material to be used, the estimate of mold maker hours, and the labor/overhead rate.

Price = Material + (Hours X Rate)

The steel quoted will determine the material price and moldmaker hours required. Although the steel or material cost typically amount to only 10% of the injection mold price, the amount of time required to machine the steel is a major part of the cost. The prehard steel may be a very cost effective route if for example, the plastic to be injection mold is polyethylene, the quality of the plastic part is not “gold-plated”, and the life of the injection mold is small, such as 20,000 pieces.

If, on the other hand, the plastic part is 30% glass-filled nylon, specifies no parting line flash, and will run one million parts, Total Solution Plasticl will quote tool steel. The steel cost is marginally more expensive then prehard, however the mold maker hours required will be substantially higher.

The challenge for all buyers is to define which steel is being quoted and whether that steel will be satisfactory for the project’s objectives.  As a service to our customers, we deliver an ASSAY report with each mold showing the mold steel used.

WHAT YOU SHOULD KNOW ABOUT INJECTION MOLD STEELS

August 1, 2011 by

Injection Mold Steels – What You Should Know

high quality injection mold

In an age that demands high productivity in manufacturing, there is no substitute for high quality injection mold in your injection molding process. Given the wide variety of injection mold steels available today, proper selection must take into account not only price and traditional practice but why they are used. In order to make the proper selection, one must understand the multiple demands that are placed upon injection mold steels, depending on the specific application. There are two major categories of demands which, together, highlight 12 desirable qualities.

Injection Mold Demands

  1. Wear Resistance – Important to consider for cavity components if the plastic material is abrasive, filled with glass or minerals.
  2. Toughness (Impact Strength) – Can be an important factor in repair or component replacement cost.
  3. Compressive Strength – Needed to withstand injection mold clamping forces to minimize damage to shut off areas.
  4. Heat Treated – Needed when injection molds operate at high temperatures.
  5. Corrosion Resistance – Very important in two major aspects – first when corrosive plastics or additives are used; and second, when injection mold operate in high-humidity areas or regions where the water is particularly corrosive.
  6. Thermal Conductivity – Can have an impact on the cycle time of high-production injection mold and although it’s not often a major factor in selecting mold steels, it is a reason for choosing beryllium copper instead of steel in some cases.

Injection Mold Makers Demands

  1. Hobbability – Permits production of numbers of intricate injection mold cavities. With the use of EDM (Electrostatic Discharge Machine), hobbability is becoming less important.
  2. Machinability – Of great economic importance for the injection mold maker.
  3. Polishability – Cavities that require a mirror-like finish must be made of special injection mold steels.
  4. Heat-Treating Dimensional Stability – A steel with good dimensional stability must be selected.
  5. Weldability – An injection mold steel should be considered because of part design and engineering changes or repair because of tool damage.
  6. Nitriding Ability – Nitriding gives a very hard surface layer to the steel and very good resistance to abrasion or corrosion. However, the nitriding layer (2 to 10 mils thick) is very brittle and easily cracks if subjected to impact blows, rapid temperature changes or uneven pressures.

Better Plastic Injection Mold Sourcing. Is It Worth The Trouble?

August 1, 2011 by

Low Cost Injection Mold

Original Equipment Manufacturers (OEMs) have to be good at what they do to survive in the global economy. To achieve this many demand that their suppliers have state-of-the-art molding equipment and procedures. OEMs can purchase some of the world’s best plastic materials from American manufacturers. When it comes to buying injection mold, OEMs have shown a preference for low-cost over high quality. This is counterproductive, as world-class molding requires a state-of-the-art injection mold.

They have been seeking low cost Injection Molds from China, India and many other low cost centers for some years now. China has put in the necessary infrastructure to support the mold building industry in the Shenzhen area. In spite of that fact, lower cost shops have opened in other areas like Shanghai, Dongguan in Guangdong, and Huangyan. Labor costs are lower and so is the skill of the workers. It is my professional opinion that no-one should ever gamble and go to areas beyond Shenzhen if they are seeking high level craftsmanship and Injection Molds that will last as per SPI Standards.

OEMs and Molders receive spam email each day soliciting their mold business. Many of these emails come from minor shops of which reside in areas that are not well supported. As long as everything goes well, it may be ok… but when there are issues, these shops do not have the technical ability nor the financial where withal to support it. We often hear customers talking about how badly they were hurt by a China shop. When this is explored further, you find that many times they went to small, unsupported, financially unstable shops which presented to them a very attractive cost. The cost did not end up low.. but very late and very expensive for the repairs. Total cost of acquisition can be deceiving.

Injection Mold – Total Solution Plastic

This is why it is extremely important to deal with Hybrid shops like Total Solution Plastic that has been to China, met the people and qualified the shop. Agreements are in place to support each other and ultimately our customer. This may cost a little more than going to the lower cost centers, but Quality Assurance, Financial Stability and Project Management is paramount when making such an important decision for your company.
