After more than two decades of industry dedication, Taizhou K - SHOW has steadily expanded its mold application fields.

On the coast of the East China Sea, by Yongning River, Huangyan is known as the "hometown of molds". K - SHOW (Keshuo Molding) was born here. In 2000, the predecessor of the company was a small workshop with only more than 20 people, renting a 500 - square - meter simple factory building. Today, the factory covers an area of 20,000 square meters, employs 110 people, and produces an average of 200 sets of large - and medium - sized automotive plastic molds per year, with an annual output value of 120 million yuan. Without capital support or mergers and acquisitions, the growth curve of more than 20 years is accumulated by one machine after another, one set of molds after another, and one trial - mold data after another.

I. Location and hardware: turning "geographical advantage" into "precision"

Huangyan is 20 kilometers away from Taizhou Luqiao Airport and 5 kilometers away from Taizhou High - speed Railway Station. Raw materials and export goods can reach Ningbo Port or Wenzhou Port directly in 4 hours. Relying on its geographical advantage, the company has introduced a series of high - precision equipment, including 105V high - speed machining centers, CNC deep - hole drilling machines, double - head electric spark machines, five - axis high - speed milling machines, and gantry machining centers. The total equipment investment has exceeded 60 million yuan. The deep - hole drilling machine can process the maximum depth of 1800 mm with a hole diameter tolerance of H7. The five - axis milling machine can achieve high - speed cutting of 6000 r/min, with a surface roughness of Ra≤0.4 μm, providing a benchmark precision for large - scale complex deep - cavity molds. The hardware upgrade did not stop at "buying equipment", but was bound with the process: each machine is connected to the MES system to transmit real - time data such as tool life, spindle load, and temperature and humidity, reducing human intervention and keeping the one - time qualification rate of processing at 98.7%.

II. Products and processes: finding a balance between "large" and "thin"

Automotive interior and exterior plastic parts must meet both styling and environmental cycle requirements, so mold design must consider both strength and lightweight. K - SHOW's main products include bumpers, instrument panels, grille, door panels, and ABC pillars, with mold weights ranging from 3 to 35 tons and the largest mold size of 3200 mm×2000 mm×1800 mm.

1. Deep - cavity bumper mold: adopts a double inclined top + internal core pulling structure, with a top - out stroke of 650 mm and a cavity depth of 870 mm, reducing cooling time by 18%.

2. Thin - wall door panel mold: the product wall thickness is 1.8 mm. The mold uses a sequential valve hot runner and high - pressure nitrogen assistance, reducing the molding cycle from 65 s to 45 s and keeping the flatness at ≤0.5 mm.

3. High - gloss grille mold: the cavity is polished to a mirror finish of #8000, combined with a mold temperature machine at 180 ℃ constant temperature, with a product surface gloss of ≥95 GU, which can directly cancel the coating process and meet the Audi exterior requirements.

Each set of molds must pass three trial - mold tests before leaving the factory: T0 verifies the structure, T1 verifies the size, and T2 verifies the batch stability. The three sets of data are automatically compared with the original CAE report. If the deviation exceeds 0.1 mm, the design will be traced back to ensure that the delivery is ready for mass production.

III. Customers and cooperation: turning "entering the system" into "long - term companionship"

Entering the whole - vehicle factory supply chain requires a pass, but more importantly, it requires long - term fulfillment. K - SHOW has successively passed the IATF 16949, ISO 14001 and ISO 45001 system certifications, and has won the Volkswagen Class A supplier and Geely Excellent Quality Award. The customer list covers Audi, Volkswagen, Ford, Toyota, Geely, Chery, Changan, Hongqi, etc. The project cycle and platform data are shared, and the mold development can be frozen synchronously with the body.

In 2019, a front bumper project of a German - class B car was delayed due to a change in styling, resulting in insufficient cooling and a warp exceeding 0.8 mm. K - SHOW completed the cooling scheme reconstruction in 48 hours, added 120 meters of conformal waterways, and used 3D - printed inserts. The second trial - mold was qualified, helping the customer to maintain the SOP node. Such "fire - fighting" cases are not worth boasting about, but they have become the basis for customers to prioritize the new platform. In 2023, the company has participated in the synchronous development of seven whole - vehicle platforms, accounting for 46% of sales, and has locked in orders for the next five years in advance.

IV. Management and talents: turning experience into standards and continuously replicating the standards

The mold industry relies on experience, but experience often flows with personnel. K - SHOW uses three steps to turn implicit knowledge into explicit standards:

1. Template - based: The 2000 historical molds are divided into 580 standard modules, and a parameter library is established. The design call time is shortened by 30%.

2. Digitalization: Introduce a closed loop of PLM + MES + CMM. The electrodes, steel materials, and detection data are all associated with one code. The version error rate is reduced to 0.2%.

3. Team building: In cooperation with Taizhou Vocational and Technical College, the "Keshuo Class" is established to input 30 technicians trained by the dual - system every year. Internally, the "technician → supervisor → project manager" three - channel system is implemented. 70% of the middle - level managers are promoted from the front - line, and the average tenure is 7.5 years.

The stable talent structure makes the increase in output value no longer rely on "adding people". In the past five years, the sales growth rate has been 9.8% per year, while the total number of employees has been kept around 110. The per capita output value has exceeded 1 million yuan, which is at the forefront of the industry.

V. Outlook: continuing to delve into electrification and lightweight

New energy vehicles shorten the development cycle, and the plastic usage per car increases by 20%, but the integration is higher. K - SHOW has started projects such as integrated high - pressure die - casting plastic inserts, laser texture 3D printing, and composite material in - mold inserts. A "lightweight forming laboratory" is jointly built with universities. The goal is to shorten the mold development cycle by another 15% while meeting the recycling requirements. The company plans to invest 20 million yuan before 2025 to upgrade the intelligent vertical warehouse and automatic assembly line, realizing online detection and automatic compensation of heavy - duty molds, and providing customers with a mold platform that iterates synchronously with the body.

After more than two decades, K - SHOW has never left Huangyan or the mold industry. In the next 20 years, there will be more variables in the industry and more complex competitive dimensions. However, the method remains unchanged: accurately measure each machining process, keep the data of each trial - mold, and meet each customer's requirements. Delving is a measure of time; expansion is a result of space. Taizhou K - SHOW is willing to work with global automotive partners to continue to write one millimeter of improvement and one kilometer of distance at the intersection of plastic and metal.
