Perusahaan kami tidak hanya mendapatkan pencapaian luar biasa pada produksi sekrup dan laras bimetal normal, kami juga telah banyak meneliti pada laras dan sekrup untuk plastik teknik khusus, untuk saat ini banyak plastik teknik menambahkan kalsium, kaolin, tanah liat merah, silika atau tambahkan serat kaca, serat karbon, serat boron dan plastik bebas halogen untuk membuat plastik asli lebih baik untuk mengadaptasi produk plastik tertentu. Di sisi lain, itu dapat membuat sekrup dan barel aus dan korosi dengan cepat, untuk menyelesaikannya Masalah ini, kami telah menemukan semacam bubuk paduan khusus, yang bahannya mengandung 25% ~ 50% wc tungsten carbide. Ini membuat masa pakai sekrup dan laras jauh lebih lama daripada jenis sekrup dan barel bimetal lainnya.
