Three 20-Station PVC Direct Injection Machines for Diamond Footcare in India

By 2023, Diamond Footcare Udyog Private Limited had three 20-station automatic PVC direct injection shoe machines supplied by Ruian Xingzhong Industrial Co., Ltd. in place at its facility in Bahadurgarh, Haryana, India.

In direct injection, PVC sole material is molded onto a prepared shoe upper in the machine, joining the sole and upper in the same production cycle. Xingzhong's customer records state that the three machines were specified against a planned output of 5,000–6,000 pairs per day. That figure is a planning target, not a measured or guaranteed result. This case explains what the records confirm and which production conditions affect the target.

Diamond at a glance

Diamond's manufacturing base in Bahadurgarh

Diamond Footcare Udyog Private Limited is registered in India under CIN U19100HR1978PTC069989 and operates from HSIIDC Footwear Park in Bahadurgarh, Jhajjar district, Haryana. Public company materials describe a vertically integrated campus of about 7.5 acres, with compounding, moulding, Hawai sheet pressing, stitching, finishing and dispatch.

The company makes non-leather footwear under the Diamond and Sisco brands, as well as several sub-brands. Third-party company databases report revenue of about ₹382 crore for the financial year ending March 2025, roughly 45% higher than the previous year. Around 886 employees are recorded in statutory filings. These figures come from public and commercial sources and have not been independently audited for this case.

Bahadurgarh is described as India's largest non-leather footwear cluster, accounting for close to 60% of national non-leather footwear output. Diamond also manufactures for established brand owners: Bata India product listings identify Diamond Footcare Udyog Private Limited as the manufacturer of certain Bata styles.

Three 20-station machines in place by 2023

Xingzhong customer records confirm three machines, each with a 20-station configuration, automatic operation, PVC material and direct injection construction. The records place the machines at Diamond by 2023.

On a rotary machine, the stations carry mould positions through the production sequence. Their number helps shape the machine's working rhythm alongside injection, cooling, operator tasks and downstream handling. It does not determine finished output on its own.

Project support

Xingzhong manufactures direct injection shoe machinery and provides technical support. Its wider product offering also includes shoe moulds and PVC and TPR materials. For any project, installation, commissioning, operator training, mould matching, spare-parts supply and remote or on-site support should be discussed and defined for the specific order.

The available customer records do not confirm the detailed service scope agreed for Diamond. This case therefore does not attribute a particular commissioning, training or after-sales arrangement to the installation.

How to interpret the 5,000–6,000-pair daily target

The 5,000–6,000 pairs per day figure was a planning target used during equipment selection. Dividing it among three machines gives an allocation of roughly 1,700–2,000 pairs per machine per day. This arithmetic does not show the actual output achieved.

A factory's results depend on the full production setup. Shoe style and size range affect cycle time. Upper construction and preparation affect how consistently the upper sits in the mould. PVC formulation influences filling, cooling and shrinkage. Mould availability and changeover time determine how much of each shift is spent moulding. Shift patterns, staffing, finishing, inspection and packing must also keep pace with the line.

To turn a daily target into a machine proposal, buyers can begin with shoe samples, the size range, upper construction, PVC requirements such as colour, hardness and density, and the available shifts. These details help the supplier review a suitable machine, mould and material combination.

Choosing direct injection for a non-leather footwear mix

Non-leather footwear factories often use several processes. EVA injection, PVC direct injection and pressed Hawai sheets serve different products and price points; Diamond's published equipment overview reflects this varied production mix.

PVC direct injection is used for footwear styles in which a PVC sole is molded onto the upper. Applications can include school shoes, casual footwear, and some work and sports styles, depending on the product design and production requirements.

When reviewing an automatic machine, buyers should consider station count alongside the intended sole, injection requirements, mould cooling capacity, drive and control systems, and compatibility with existing moulds and lasts. The right configuration depends on the footwear and factory conditions; station count alone is not a production guarantee.

Three planning lessons for PVC footwear factories

• Start with the shoe. Samples, size range, upper construction and PVC requirements give the supplier a basis for reviewing the machine and mould configuration.
• Treat station count as one part of the production rhythm. Material, moulds, shifts and operator coordination also affect output.
• Plan downstream capacity. Finishing, inspection and packing need to handle the flow from moulding, or they can become the production bottleneck.

Frequently asked questions

What did Diamond purchase from Xingzhong?

Xingzhong customer records confirm three 20-station automatic PVC direct injection shoe machines, in place by 2023. The records do not disclose a public model number or contract value.

What is a PVC direct injection shoe machine?

It molds PVC sole material directly onto a prepared shoe upper, joining the sole and upper in the same production cycle rather than in a separate bonding step.

What output was planned for the three machines?

The machines were specified against a planned output of 5,000–6,000 pairs per day, or roughly 1,700–2,000 pairs per machine as a simple allocation. This is not a measured result or a performance guarantee.

Where is Diamond's factory?

Diamond Footcare Udyog Private Limited operates from Plot No. 345, HSIIDC Footwear Park, Sector-17, Bahadurgarh, Jhajjar district, Haryana, India.

Does Xingzhong provide moulds and material support?

Xingzhong supplies shoe machinery and moulds, and discusses PVC and TPR material requirements with customers. The specific products and services for a project depend on its agreed scope; the customer records available for this case do not confirm further details.
