Titanium Powder Metal Injection Molded Half Round Golf Head MIM Parts

Any mechanical components need to be lightweight and high-strength, and titanium is a priority. Most titanium alloys have similar strength to steel, but are 40% lighter. Therefore, many aviation and medical equipment use titanium.

The general design weight of the club head is about 190-200 grams, so using titanium alloy can make the capacity larger than that of steel. Generally, steel can only achieve 310-320cc due to weight restrictions. But titanium can achieve 500cc and maintain the weight at 190-200 grams. In addition, titanium alloy has strong rigidity and can produce more spring effect when used on the club face.

When choosing titanium metal to make club heads, there are several key points to consider the characteristics of various alloys:

Yield Strength Tensile resistance: How much force an object needs to bend or deform. Use PSI (pounds per square inch) or KSI (thousand pounds per square inch) as the measurement standard. This data is an important reference for the club face and club head structure.

Tensile Strength Pressure resistance: How much force is required to break an object, measured in PSI (pounds per square inch) or KSI (thousand pounds per square inch). This data is also an important reference for the club face and club head structure.

Hardness: The hardness of the surface of an object. Hardness is very important to all structures of the club head, especially the club face.

Elongation: refers to the ductility of an object. The higher the index, the greater the elongation of the object without breaking. It is an important index for the club face and top cover.

Modulus stretch rate: refers to the compression and tension of an object. The higher the index expressed in PSI, the harder the object. Very important in design. Because this number determines how much force the clubface can withstand before twisting/breaking.

Fatigue Strength Metal fatigue: represented by PSI, is very important to the club face. Because it is necessary to prevent metal from cracking under long-term heavy use

Poisson Ratio: When the material is stretched longer, the material can

When titanium alloy is heat treated, many values will change (for example: 6-4Ti will have a pressure resistance difference of 120,000 to 170,000 psi after heat treatment), so a good club head not only needs a good design, but also The steps and control of materials during manufacturing are also important.

The method used by Qinhuangdao Zhongwei Precision Machinery Co., Ltd. to manufacture titanium alloy golf heads is metal injection molding and investment casting. Generally, metal injection molding ball heads are mixed with pure titanium powder and binder.

Step 1: Use titanium powder to granulate. Add titanium powder, grease release agent and resin adhesive to the mixer and mix evenly to granulate. The addition ratio of titanium powder, release agent and adhesive is: 90% titanium powder, 10% release agent and adhesive.

Step 2: The stirred titanium powder is injected into the injection molding machine for injection molding.

Step 3: Put the formed preliminary embryo into the temperature control box for low-temperature preheating and shaping, and set its temperature to 170°C.

Step 4: Put the shaped preliminary embryo into a high-temperature furnace for high-temperature sintering and molding. The temperature is set to 1200°C.
