1.Grundfos' Selection Of Investment Casting Manufacturer – Lin Chiao Casting Co., Ltd.

Grundfos' Selection of Investment Casting Manufacturer – Lin Chiao

In 2014, the cooperation between Lin Chiao and Grundfos is going one step further; Lin Chiao is no longer just an investment casting OEM manufacturer. Instead of just fabricating pumps based on Grundfos' design, after years of working together, Grundfos now would first provide a sketch followed by a lengthy discussion about the technical aspects based on the design. Finally, Lin Chiao delivers a final design according to the discussion. It is a statement about how Grundfos respects Lin Chiao's professionalism, and Lin Chiao's performance has been fantastic.

The world-class investment casting manufacturer Lin Chiao has received 30-ton pump orders from Grundfos Taiwan, one of the world’s leading pump manufacturers in Dammar.

casting process

Opportunity is for people who are ready. When Grundfos was looking for an investment casting manufacturer, Lin Chiao was all ready for the job.

The first procurement was made 7-years later after Lin Chiao delivered 9 sample pumps at the beginning. Seven years of communication and evaluation seems long, but the result was delightful. Grundfos' recent 30 tons pump order was an acknowledgement of Lin Chiao's investment casting skill.

Seven years ago, Grundfos was cooperating with a fairly big metal casting company using sand casting to make pumps, however, lost wax casting's advantage attracted them to switch to lost wax casting. Pinholes occurred during lost wax casting process; hence, Grundfos had to look for other suppliers for solutions.

When the manager of Grundfos showed up at the door with a large pump after a long drive all around Taiwan searching for an investment casting manufacturer, he asked Lin Chiao whether they can do it or not. He mentioned about the pinhole dilemmas with the other manufacturer, and would like to hear about the solutions.

Lin Chiao explained and proposed the pinhole solutions and Grundfos had Lin Chiao to make the samples. As a result, Lin Chiao had surpassed their large competitors and won the competition because of the high quality stainless steel pumps they made.

Based on the pump from the manager of Grundfos, a large wax injection machine that would allow 500mm*500mm mold size was required. Lin Chiao fabricated 9 pumps for Grundfos, and the pumps were tested for two years. While Lin Chiao was wondering about the test results, two years later, Grundfos asked for a quotation. After submitting the quotation, Lin Chiao waited for another two years and finally heard back from them. Grundfos made the first order from Lin Chiao; it was the first time after four years of waiting and Grundfos took it very seriously.

From mold making, sample testing, small amount production, different sizes of pump fabrication until the recent 30-ton pump ordering, it was a seven-year period of assurance.

For seven years, Lin Chiao has been performing high standard investment casting technology and providing professional consulting based on 24 years of seasoned experience.

2.Investment Casting For The Largest Orthotics Prosthetic Parts Supplier In The U.S.

Lin Chiao's Investment Casting For The Largest Orthotics Prosthetic Parts Supplier In The U.S.

In the U.S., there are five big orthopaedic device companies, and Orthomerica Products, Inc. is the largest compared to others. Orthomerica Products delivers the most functional and comfortable orthotics prosthetic parts for muscle weakness and paralysis of body parts.

Orthomerica Products visited a few OEM lost wax casting suppliers in Taiwan and asked for completed SGS reports, but not every supplier passed the tests.

For prosthetic and orthotics components, investment casting metal-forming technology is applied to ensure each device's safety. Because of orthotics prosthetic parts' complex shape, one-piece casting is required. Therefore, a skillful lost wax investment casting manufacturer is critical importance.

After a series of rigorous assessments, Orthomerica Products chose a Taiwanese investment casting manufacturer, Lin Chiao Casting Co., Ltd., above other competitors. At the beginning, Orthomerica Products' was procuring half of the orthotics prosthetic parts from Lin Chiao, years later, due to their excellent performance, it is now 100% supplied by Lin Chiao.

Prosthetic and orthotics components metal casting

Since investment casting was discovered, the industry has grown steadily because of the low tooling cost, time saving, better finishing and the optional alloy choices. Investment casting allows you to choose various sizes of orthotics and prosthetics, from stainless steel hip orthoses to foot and ankle orthoses, and it also delivers great safety for the users.

Particular for orthopaedic device, while the world economy continues to face its difficulties, the healthcare sector in general and the orthotics prosthetic parts industry in particular is growing strong. For the level of detail and precision necessary for metal orthotics prosthetic parts, Lin Chiao uses the lost wax casting technique to meet tough requirements.

Orthomerica

Orthomerica Products have chosen Lin Chiao, a Taiwanese lost wax casting supplier, as a quality manufacturer of their orthotics prosthetic parts. The leg orthosis attached to a patient's leg must be supportive, functional and comfortable, and any possible injuries caused by a defeated product are unacceptable.

For Orthomerica Products, each orthosis (KAFO/AFO) should be manufactured to the highest standard and met the criteria. Therefore, when choosing an investment casting component manufacturer, requirements are extremely strict. Based on 24-years of lost wax casting experience, Lin Chiao's stainless steel component passed all of the physical tests at SGS, and fatigue tests in the U.S. by Orthomerica Products.

Special formula prosthetic orthotics components' requests

Material formula is an important factor for lost wax casting ; it affects stainless steel component's strength, torque and fatigue capabilities. To achieve Orthomerica Products' high expectation on prosthetic and orthotics components, control of slurries, material formula adjustment and experiment were performed consistently.

Investment Casting Manufacturer, Lin Chiao, Overcome 25-Day Lead-Time Request To Win Client's Heart

"You can't predict who's your next big client, you can only grasp every opportunity to prevent missing one." said the president of Lin Chiao. One evening, Lin Chiao, a Taiwanese investment casting manufacturer, received a call from Magnate Technology Co., Ltd. who requested bottle clamp fabrication using lost wax casting technology.

The manager asked a few questions on the phone: "What's your company's product development ability? What's your production lead-time? What's your monthly production capacity?" and also claimed that they had been cooperating with another metal casting company for a long time, but their low volume production wasn't favorable and their worsening casting performance made the customer search for other solutions, but there was only 25 days left before delivery. Normally it takes about two months to finish the whole casting process and Lin Chiao was asked for a 25-day lead-time. After a short discussion, Lin Chiao took the job.

7 days mold making. 3 days rapid prototyping. 2 days tooling. – fast and high quality investment casting

From understanding the design, discussing the manufacturing possibility, mold designing and making, product prototyping to massive production and testing; achieving all the jobs in 25-days is crucial, and manufacturing 100% perfect products with high tolerance is just as important. Therefore, every investment casting process requires precision, and the machine has to be in the great condition. After the goal was set, mold design and making was done in 7 days, prototyping was done in 3 days, tolling was done in 2 days, plus SGS testing and packaging, etc.

Factors for making perfect lost wax casting product

casting process - pouring

There are many casting process factors which affect wax casting tolerances, including wax temperature, firing temperature, die temperature, pressure of injection, shell composition strength, rate of cooling, etc.

Particularly in shell composition, when the shell is placed into an oven where it is fired for a period of time, the solidness of the shell affects the next process, which is when molten metal is poured into the shell. Great shell strength causes high quality product stability. Since the shell's soundness is decisive, if the shell can't handle the melton metal and the shell breaks or inflates, so humidity control has become critically important for steel investment casting.

At Lin Chiao, investment casting process environment control is enhanced by applying a vacuum or minimizing the humidity to conduct a perfect shell condition.

Short Lead-Time. Sell Without Inventory Casting Process

Nowadays, buyers require short lead-time and sell without inventory. To fabricate machine equipment using investment casting technology in 25 days and get results with high quality production, process management standardization becomes critically important. After knowing the fabrication possibility of bottle clamp, each process' execution period is set and performed exactly.

4.No More Sand Casting For Big Object, Investment Casting Is The Future

No More Sand Casting For Big Object, Investment Casting Is The Future

HYDAC is a worldwide supplier of fluid power solutions and their products cover a wide range of mobile and stationary mechanized equipment. Because of the large size of pumps and valves for fluid power components, they were originally using sand castings to fabricate the equipment; however, the advantages of investment casting prompted them to change. Lin Chiao is a Taiwanese lost wax casting manufacturer and was selected by HYDAC for the transition.

Since the casting process was specifically designed for sand casting, Lin Chiao had to modify the process to meet lost wax casting's process criteria.

"It wasn't all that smooth switching the process from sand casting to investment casting; the design of sand casting might be too thick or too thin when applying to lost wax casting's process, so the adjustment was essential. Our casting engineering team had to upgrade their technologies in order to manufacture the equipment, it was a learning experience." said by the manager of Lin Chiao. As a consequence, Lin Chiao's casting equipment was tested as level II after conducting x-ray fluorescent chemistry test, which met HYDAC's high quality policy.

There were two important issues that influence cost in lost wax casting project, the production time and the cost in production. To save production time, you will need a quality casting manufacturer to provide correct judgments based on the sustained casting experience and Lin Chiao's 24-year of metal casting experience can assist you to achieve your goals.

Rigorous and Innovative Casting Process - Step 1: Wax Pattern Making

Investment Casting Engineering Team - Cast-Friendly Design

When Lin Chiao's engineering team receives a product design from a buyer, Lin Chiao's engineering team would gather together to discuss the melting point and to find out the possible difficulties during casting, and managers from each department will have a meeting to discuss the casting process from their perspective.

Lin Chiao's 24-years of alloy casting experience allow them to come up with innovative solutions to provide an accurate and versatile investment casting process.

High Quality Investment Casting Mould Making
High quality investment casting mould making

Lin Chiao has accumulated more than 20,000 molds after being a wax investment casting manufacturer for 24 years. Building a metal casting mold is different compared to others; you need a place where the alloy is poured into and mold maker needs to understand the concept of how to build a mold when the shape complicated.

Rapid Prototyping

Lin Chiao offers rapid prototyping for investment casting in a variety of alloys including stainless steel, carbon steel, nickel steel, iron casting, etc. When you receive Lin Chiao's rapid prototyping, the product is fully developed. Lin Chiao provides flexibility in production quantities, whether for a quick rapid prototype solution, small production or a high quantity ordering.

Wax Pattern / Wax Injection Condition, Time and Stability

When injecting wax into the mold, the wax pouring pressure (7~12kg/cm² or 50 kg/cm²), pre-heat mold temperature, wax injection time and temperature, wax pattern injection room temperature and the mold cooling method after wax is injected are the important factors for the wax injection process. Therefore, there are decisions that need to be made, and unprofessional judgment can lead to poor results. At Lin Chiao, water soluble wax, which can be dissolved in room temperature, is applied to the parts or angles that are hard to remove from the wax.

Wax Pattern Assembly

Once cooled, the wax pattern is removed from the mold, staff would remove the burrs on the wax pattern and make sure the surface is clear. When are they done, they are ready for casting tree fabrication.

Casting Tree and Sprue

Every wax pattern can be processed individually depending on component size. They are attached to a wax runner and joined with a pouring cone, which is called casting tree or pattern cluster. Every wax pattern can be processed individually depending on component size. The wax patterns are attached to a wax gating poll with a runner, and the whole thing is referred to as a tree, pattern cluster or sprue.

Rigorous and Innovative Casting Process – Step 2: Ceramic Slurry and Stucco

Shell Making of investment casting process – Dipping
shell making of investment casting process

Shell making is a paramount step; if you fail to make the shell, the whole lost wax casting process is ruined, therefore, the strength of the shell has to be strong enough to handle the following process. Ceramic shell is a combination of ceramic slurry, which contains colloidal silica, alumina, stucco, etc. The tree is dipped in the ceramic slurry for the suitable thickness; it is the first preparation for molten metal pouring processing. The casting tree is dipped in silica gel for better attachment on ceramic slurry dipping.

Sand Coating (Stucco)

After the ceramic slurry dipping, the whole tree is coated with sand which is called stucco. The ceramic stucco procedure is decided during the engineering meeting. There are six times of ceramic dipping and ceramic stucco, and the stucco process started with the thinnest sand to the roughest sand. It takes about three days to finish the whole process between the drying time and procedures. The drying process is performed in an adequate time to avoid cracks. There are various sand coating methods and it depends on the density requirement.

Rigorous and Innovative Casting Process – Step 3: Shell Mold Firing

shell mold firing casting process

Casting mold firing time and temperature are decided during the meeting based on years of investment casting experience. Investment casting molds are fired in an oven at 1800 degrees Fahrenheit using steam to remove any volatiles. The molds are removed from the oven and placed on a support device and are ready for molten metal pouring. Melted wax is recycled for the next usage.

Molten Metal Pouring

The liquid metal is poured in an investment casting shell; time and temperature are important factors for this step.
